Illion Numbers by Jonathan Bowers (Recontinued)

Illion Numbers by Jonathan Bowers (Recontinued)

We're all familiar with numbers like million, billion, or trillion - but how far do the "illion" numbers go, the furthest I've seen in the literature is milli-millillion (10^3000003) which I call a micrillion. Some time ago (about 15 years or so), being interested in giant numbers, I have invented names for illion numbers past a centillion (highest that I've seen in books at that time) - by continuing the trend: deci, centi, by using milli, micro, nano, pico, femto, and atto. Sometime later, I found out that I wasn't the only one to choose the name "millillion" for 10^3003 - I found this name mentioned on Robert Munafo's fascinating web site on large numbers. Following is a list of the "illion" numbers (those above millillion are names I invented), along with googol, googolplex, and googolduplex for size reference. The ones less than micrillion are shown on the above mentioned web site, naming rules up to the millillion range are mentioned in The Book of Numbers by Conway and Guy. I recently changed some of the numbers to match with the polytope suffixes. In 2022, due to the new prefixes ronna, ronto, quetta, and quecto, I changed a few illion names. In 2024, correction made for location of googoltriplex and bentrizillion as well as a note on the later, thanks to Sbiis Saibian, and due to XRQ's Money Prefix System, I might as well channge some of the illion names. In 2025, brunta, bramto, agana, and azeko are about to be added, so I'm gonna change a few illion names again
