User:BartekChom/Googolgoogolplex

Googolgoogolplex can be equal to 10↑↑(10100) (another name for googol-stack) or to the googolth element of the sequence googolplex, googolduplex, googoltriplex..., i.e. a10100 for a0=10100 and an+1=10an.

In the second sense it was published on 10 June 2018 on the old wiki by user‎ Eners49 and on 4 April 2021 by BartekChom under the Polish name gogolgogolpleks. It can be denoted in less standard but more compact ways, e.g. as
 * {10↑↑10100}↑{10100} = {10↑↑(10100+1)}↑{100} = {10↑↑(10100+2)}↑{2} using a convention by Sbiis Saibian
 * 10 ↑↑ 10100 ↑ 10100 = 10 ↑↑ (10100+1) ↑ 100 = 10 ↑↑ (10100+2) ↑ 2 if interpreted as different from numbers like (10 ↑↑ 10100)10 100 and 10 ↑↑ ((10100)10 100 )
 * (10^)10 100 (10100) = (10^)10 100+1 (100) = (10^)10 100+2 (2) using function composition and an ad hoc created function (10^)(n)=10n
