1.5 - Bowers' illions and extensions
Introduction
Most of the googologists (even me) looked at -illions by Jonathan Bowers, who is well known for its array notation and other large numbers. The original Bowers' -illions consist of 4 tiers, which end with multillion. There are some of the attempts to extend the -illions beyond multillion. Here is the link to the original -illions by him.
There, most of the -illions are based off of polytopes, as he is also well known for his work in polytopes.
Note that he uses short scale for the -illions, but I will add the long scale equivalent as well.
List of the -illions that Bowers defined and listed
The list is collapsible, click/tap on arrow to expand/collapse.
The standard -illion names are highlighted in blue.
The -illions highlighted in cyan represent the established -illions other than Bowers.
The popular numbers that are not -illions are shown in dark red.
The -illions that are mentioned to Bowers, but does not know where it is originated, are highlighted in purple.
The -illions that are coined by Bowers himself, are highlighted in green.
I also added the long scale value (until micrillion, to prevent ambiguity) into the list.
