This page documents the many derivatives of Googol.
THIS LIST IS A WORK IN PROGRESS
Base
Most extensions of Googol were coined by Johnathan Bowers and are based around his notation Bowers' Exploding Array Function, or BEAF, which Bird's Array Notation (BAN) is based on. Each extension will be defined based on how it affects Googol written in BEAF. (Because BEAF and BAN are initially identical, BEAF is referred to as BAN in the notation reference below.)
Notations
Scientific/Knuth's Up-arrow/Operator/BAN
(Notations will be dropped as they become impractical for writing the number)
Googol
10^100/10↑100/10{1}100/{10, 100}
Tier 1-Suffixes
These replace the 100 with a larger power of 10 like so:
-chime - 1,000 -toll - 10,000 -gong - 100,000 -bong - 100,000,000 -throng - 100,000,000,000
You could possibly keep going with -quadrong for 100 trillion, but these are the ones seen in MathisR.V's video.

Tier 2--plexes
These replace the 100 with nested Googols (or later variants). They use Greek/Latin prefixes in their names counting how much nesting there is. -triplex adds -duplex, -quadriplex adds -triplex, etc.
Googolplex
(the only officially recognized Googol extension)

(At this point, the notations get so long that Up-Arrow and Operator Notation have to be compressed to fit on one line of text.)

yes i know that's the same banner from the main index. don't judge
