• ## My New Numbers!

April 17, 2019 by XYZeed

I just started getting into googology again and I have created 2 numbers since. The first one is called Jonah's Number (My name is Jonah Nichols) and it is equal to 1.919...x10^10^200.

My next number is much larger and is called Ultra Behemoth. It is equal to 10^^^10^^10^1500. Comment what you think of them or maybe even make pages on them!

Updatd: I made a third number called goggle which is equal to {10,10^100,100}

• ## : notation up to linear arrays

April 17, 2019 by Ynought

This will (hopefully) be my most refined (recursive) notation

$$\#_k$$ is the labeled rest of the notation

$$\{ \text{and} \}$$ is any amount of ( ) brackets

$$a$$ will always denote the number before the $$:$$

$$\#_i\rightarrow\#_j$$ means $$\#_i$$ turns into $$\#_j$$

$$f_0(c)= (c+1)^{c+1}$$ and $$f_k(c)= f_{k-1}^c(c)$$ where $$f^0_k(c)=c$$ and $$f^{d}_k(c)=f_k(f_k^{d-1}(c))$$

This is the 1st part of ? parts and it is the most simple

$$a:=a$$

$$0:\#=0$$

$$1:\#=1$$

$$a:\#_1b\rightarrow f_a^a(b):\#_1$$

Start looking from right to left until you find a number inside a pair of bracket.Call that number $$b$$.Then:

1.If $$b=0$$ then $$(b)\rightarrow a$$

2.If $$b>0$$ then $$(b)\rightarrow(b-1)(b-1)...(b-1)$$ with (in total) $$a$$ $$(b-1)$$'s

This may seem like a silly project because it took me ~6 seconds to factor 21 (3*7) and it printed the number in unary. This project is studying the amount of time that it takes to factor each semiprime that is: 1. Greater than or equal to 21 2. The larger factor is less than 1.6 times the square root. 3. The semiprime is at least 3 integers away from the last prime being tested. Because we are not testing the ability to factor, we are testing the number of steps required to factor and dividing it by the number. This function, so far, has not grown that fast. But, because of the way that busy beavers behave, I believe there is a possibility that it is an uncomputable one. 21: 2… Read more > • ## Googology Tale: There Was an OCF Which Collapsed an Ordinal (culumative song parody) April 14, 2019 by Nayuta Ito There was an OCF which collapsed an ordinal; I don't know why it collapsed an ordinal - on purpose it'll be ill-defined!

But it is not true: there are real numbers, and some of them are not rational. Set of rational numbers is countable, and set of real numbers has cardinality of continuum. And I asked myself: is set of real numbers the most "dense" in (-∞; +∞)? Or maybe there are numbers in (-∞; +∞), which are not real, and cardinality of set of them is larger than cardinality of continuum? (Maybe, some of these numbers are located "between" reals, the same way as some of reals are… Read more > • ## Attempt at an ordinal catching type function April 13, 2019 by Ynought So if this definition doesn't work in any way then please tell me what is wrong with it. \(f$$ is the FGH

$$g$$ is the SGH

when i say $$f_\alpha(n)\approx g_\alpha(n)$$ i am saying that for that $$\alpha$$ there exists an$$n$$ for which holds $$g_\alpha(n+1)\geqslant f_\alpha(n))$$

$$\gamma(\beta)$$ is the ordinal needed that $$g_\alpha(n)\approx f_\alpha(n)$$ is the case for the $$\beta$$'th time

the way you get that for succesors is easy but if you come across a limit then :

$$\eta$$ is the limit ordinal which you come acros

so when $$\alpha=\eta+\delta$$ then $$\gamma(\alpha)=\gamma(\eta[n]+\delta)$$

$$f_\alpha(n)\approx g_\alpha(n)$$ means $$\exists(n|f_\alpha(n)\leqslant g_\alpha(n+1))$$

for $$\alpha=\delta+1$$:

March 24, 2019 I published 9 lists of ordinals, generated using v3.0 of my program. Bubby3 (thank you Bubby3!) wrote in a comment that I skip many ordinals like [[[M][M]][M]][[M][M]] = psi(W_2+psi_1(W_2)) = psi(e_(W+1)*2) and [[[[[M]M]]M][[M]M]] = psi(psi_I(0)*2). In that blog I wrote that limit of these lists is "Rathjen ordinal" (#1201 in Scorcher007's list of 2000 ordinals), but it meant that this limit is lesser.

A lot of you will object and say "It doesn't work" and will not analyze it. However, there is no function that is as strong as behaves the same. So, I am going to analze second generation SAN anaway, despite what people say. With any non-working notation, there are two strength, it's working and hyphoteical. Iyts working strength is how the notations which don't produce a loop and terminate are. Hypothecial strength represents how strong would it be if it were fixed, and it didn't loop and always halt. Almost always, the hypotheical strength is much stronger, but there can be excpetions, namely where a problem causes the notation to be stronger than expected, then causes it to loop after that.

$$E$$ function takes place on a plane with starting point $$(0|0)$$ at the bottom left corner and the thick ness of the line is $$n^{-n}$$ and the lenght is $$n^{-1}$$.And the size of the units doesn't matter

$$\alpha_n$$ is the angle that line nr.$$n$$ deviates from the x plane

$$G_1$$ is the starting graph.And $$G_i$$ is the graph that appears if you repeat the rules for the transformation of $$G_1$$ for the $$i$$-th time

$$\star$$ denotes homeomorphical embeding lets say i.e. $$G_i\star G_j$$ means that $$G_i$$ is homeorphically embedable into $$G_j$$

$$\omega=\text{sup}(0,1,2,3...)$$

• ## Recursion and Summation Functions

March 25, 2019 by B1mb0w

I use short hand notation for recursion of nested functions. They are a further development of notation I use that is not in common use.

Here is a summary review of my notation:

Decremented Function $$C$$ is short-hand notation. For any arbitrary function:

$$M^{c + 1}(n)$$ then $$C = M^{c}(n)$$

e.g.

$$M^{c + 1}(n) = M(C) = M(M^c(n))$$

Parameter Subscript Brackets is shorthand for functions with multiple parameters:

$$M(x,0_{[2]}) = M(x,0,0)$$

$$M(x,y_{[2]}) = M(x,y_1,y_2)$$

$$M(x,0_{[2]},y_{[3]},z) = M(x,0,0,y_1,y_2,y_3,z)$$

Leading Zeros Assumption applies to any function I define which accepts a variable number of input parameters. All leading zeroes can then be ignored:

$$M(0_{[x]},0_{[2]},y_{[3]},1) = M(0_{[x + 2]},y_{[3]},1) = t_0(y_{[3]},1) = M(y_… Read more > • ## 9 lists of ordinals up to Rathjen ordinal (total 12321 ordinals) March 24, 2019 by Rgetar This is annex to New program (ordinals up to Rathjen ordinal) blog with lists of ordinals, generated using Ordinal Explorer v3.0.

Throughout this blog post, a function means a map $$\mathbb{N} \to \mathbb{N}$$, and I denote by $$\textrm{Func}$$ the set of functions.

• ## Hyper Tower Notation, Pt. 1 (Inspired by Hyper-E notation)

March 18, 2019 by GamesFan2000

Hyper Tower Notation is an exponentiation-based notation. The expressions of this notation will decompose into power-towers.

1. ...n#1=...n

2. ...n#m+1=...n^(...n#m)

3. ...n#k+1m+1=...n#kn#k...n n’s...n#kn^(...n#k+1m); #1=#

4. ...a#mn#k+11=...a#mn#kn#k...n n’s...n#kn^(...a#mn); n#k+11=n#kn#k...n n’s...n#kn

Let’s look at some examples:

4#3=4^(4#2)=4^4^4

5#3#3=5#3^(5#3#2)=5#3^(5#3^(5#3))=5#3^(5#(3^5^5^5))=5#3^5^5^...3^5^5^5 5’s...5^5

4#4#4#3=4#4#4^(4#4#4#2)=4#4#4^(4#4#4^(4#4#4))

n#m is basically n^^m, and each new sign and term added roughly moves the expression up a hyper-operator level. n#n#n…#n#n roughly corresponds to recursion level omega(w) in the FGH.

4#23=4#4#4#4^(4#22)=4#4#4#4^(4#4#4#4^(4#4#4#4))

4#24#4=4#24^(4#24#3)=4#24^(4#24^(4#24^(4#24)))

4#24#2=4#24#4…

• ## Cascade Notation, Pt. 1

March 16, 2019 by GamesFan2000

Addition is the weakest of the hyper-operators. In the FGH, it compares to f1(n). It’s a weak notation, but it’s a great starting point for googological functions. So, let’s take 3+3+3. We have three-plus-three-plus-three. An average person can easily tell you that this is equal to nine. But, what happens when I do this: 3++3++3? Well, I’ll show you how I’d solve this:

3++3++3=3+3+3++2++3=9++2++3=9+9+9+9+9+9+9+9+9++1++3=81++1++3=81+81...81 81’s…+81++3=6561++3=43046721++2~1.853*10^15++1~3.433*10^30.

Yeah, that actually defeats 3^^3, amazingly enough. But it’s nothing compared to 3+++3:

3+++3=3++3++3+++2~3.433*10^30+++2. That’s big. So, what’s the point of this? Well, these expressions are part of my new notation, Cascade Notation. This notatio…

• ## Notation without converting into standard form. Program and lists of ordinals

March 16, 2019 by Rgetar

Let we have an ordinal notation (that is correspondence "string - ordinal"). An let we have a fundamental sequence algorythm in this notation (that is correspondence "string, corresponding to ordinal - string, corresponding to an element of fundamental sequence of this ordinal").

If we have this notation and this algorythm, is a system of fundamental sequences defined?

Maybe not. Because there may be different strings in the notation, corresponding to the same ordinal. And the fundamental sequence algorythm, applied to these strings, may produce different fundamental sequences, so we can get different fundamental sequences of the same ordinal. So, system of fundamental sequences may be not well-defined.

There may be different ways to solve th…

• ## Multiple Array Notation

March 14, 2019 by VoidSansXD

This is part 1: Beginning of One Entry Arrays

RULES:

(a) = a

(a)(1) = a+1 = f_0(a)

(a)(2) = a+1+1+1........+1+1+1 with a nests, or 2a = f_1(a)

(a)(3) = 2*2*2*2*2..............*2*2*2*2*2*a or (2^a)a = f_2(a)

(a)(x) = f_x(a) (I think).

(a)(1)(2) = (a)(a)

(a)(2)(2) = (a)(((((...(((((a)((((...(((((a)(a))(a)))......a)))))))........)))))) with a nests (Right to left)

That's it for now :D

• ## Commutatieve ackermann function

March 14, 2019 by Fejfo

This idea came from wikipedia where I read something about commutative hyperopperations, but they didn't even reach tetration so I made this.

The goal is to define a commutative hyper operation function, $$A(a,b)=A(b,a).$$

This is the definition:

1. $$A(a,b)=A(b,a)$$, from now on the first argument is assumed to be larger or equal, without loss of generality.
2. $$A(a,0)=a+1$$
3. $$A(a+1,b+1)=A(A(a,b+1),b)$$

For $$a\ge b$$ we get:

• $$A(a,0)=a+1$$
• $$A(a,1)=a+2$$
• $$A(a,2)=2a+2$$
• $$A(a,3)>2^{a+1}$$
• $$A(a,4)>2↑↑a$$
• in general $$A(n,n)$$ hase the same growth rate as $$f_\omega$$
• ## My attempt at an ordinal function

March 13, 2019 by Ynought

$$\eta$$ is any function it could even mean that nothing happens.But $$\eta$$ does not size down the input.

$$\Theta(0)[n]=n$$ and $$\Theta_0=\Theta$$ here $$\alpha[n]$$ is the n-th term in the fundamental sequence of $$\alpha$$

$$\Theta(\eta\alpha)[n]=\Theta(\eta\alpha[n])$$ if the next case does not apply.And if the $$\Omega$$ case does not apply

$$\Theta(\eta\alpha+1)[n]=\Theta(\eta\alpha)\uparrow\uparrow n$$ n times

$$\Theta(\eta\Omega)=sup(\Theta(\eta\omega),\Theta(\eta\omega+\Theta(\eta\omega)),\Theta(\eta\omega+\Theta(\eta\omega+\Theta(\eta\omega)))),...)$$

$$\eta\Omega_0=\eta\Omega$$ and $$\eta\Omega_{\alpha+1}[n]=\eta\Omega_\alpha^{\dots^{\eta\Omega_\alpha}}​$$ or $$\eta\Omega_\alpha\uparrow\uparrow n$$

Thats it for part 1?

• for $${a}$$ we have just a.
• for $${a,b}$$ we've got \(a -> a -> b times
