User blog comment:Tachyonic Encrypter/Getting bigger than Rayo's function. Is it possible?/@comment-4224897-20141120012826/@comment-1605058-20141120204335

First of all, you are missing the fact that some equations have negative answers.

Biggest possible number is not achievable, because of famous googological rule "you can always add 1".

Your number is undefined, because you did not specify the date in this case.

From your comment I still can't see how this is not going meta.
