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.
Notations
Scientific/Knuth's Up-arrow/Operator/BEAF
(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 -gandigan - 100,000,000,000,000
You could possibly keep going with -quintigong for 100 quadrillion, 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.

Tier 5 - Replacing -g-
These add (1) followed by a single entry based on the extension. The extensions themselves are the same as tier 4, but applied to the second g.
(An array ending in (1) 1 is the same as an array without any (1) separators, eg. {10, 50, 4 (1) 1} = {10, 50, 4})
