The Notation
These numbers use the notation described here.

Barr
$$Barr=[2,2]$$

Barr is a class 1 linear array of two twos. It is equal to 4.

Trarr
$$Trarr=[3,3,3]$$

Trarr is a class 1 linear array of three threes. It is equal to 729.

Quadrarr
$$Quadrarr=[4,4,4,4]$$

Quadrarr is a class 1 linear array of four fours. It is equal to 655364, or about 1.84x1019

Decarr
$$Decarr=[10,10,10,10,10,10,10,10,10,10]$$

Decarr is a class 1 linear array of ten tens. It is equal to $$10^{1,000,000,000}$$, making it a googol to the power of 10,000,000; or the trialogue to the power of one tenth.

Icosarr
$$Icosarr=[20,20,20,20,20,20,20,20,20,20,20,20,20,20,20,20,20,20,20,20]$$

Icosarr is a class 1 linear array of twenty twenties. It is equal to $$20^{5,242,880,000,000,000,000,000,000}$$

It is approximately googol to the power of 68,200,000,000,000,000,000,000.

Centarr
$$Centarr=ARR(100,100,1)=\underset{100}{[\underbrace{100,100,...,100,100}]}$$

Centarr is a class 1 linear array of one hundred one hundreds. It is equal to $$100^{100^{99}}$$

It is greater than a googolplex but still not very large relative to the following numbers...

Argol
$$Argol=ARR(10,10^{100},1)=\underset{10^{100}}{[\underbrace{10,10,...,10,10}]}$$

Argol is a class 1 linear array of a googol tens. As such, it is equal to $$10^{10^{Googol-1}}$$, or Googolduplex to the power of one-tenth.

Argolplex
$$Argolplex=10^{Argol}=[10,\underset{10^{100}}{[\underbrace{10,10,...,10,10}]}]$$

Argolplex is ten to the power of Argol. It is also equal to a class 1 array with two entries, of which the first is 10 and the second is a class 1 array containing a googol tens.

Grargol
$$Grargol=ARR(10,10^{100},2)$$

Grargol is a class 1 square array of tens with a side length of a googol.

It is equal to $$Argol^{Argol^{Googol-1}}$$
