Googolquadriplex

A googolquadriplex is a number equal to one with a googoltriplex zeroes after it, or 1010101010100.Plexing & The Googol Series - Large Numbers by Sbiis Saibian The term was coined by Sbiis Saibian. There are a few variants of the name of this number, which are unofficially coined by others or are just refered to without sources: googolquadraplex,Jonathan Bowers, Infinity Scrapers accessed 2021-12-27 googolplexianiteron,saruviel's post described as ©Haven Noahide Fellowship 2010 accessed 2021-12-27 and googolquadruplex.Antonio Padilla (2023) "Fantastic numbers and where to find them: A journey to the edge of physics" Penguin Books. ISBN 978-0141992822 p.41
In Hyper-E Notation it can be written E100#5.Sbiis Saibian's Ultimate Large Numbers List In down-arrow notation it can also be written \(10 \downarrow\downarrow (10^{10^{10^{100}}}+1)\). It is 10101010100+1 digits long. 
Writing down the full decimal expansion would take 10101010100-6 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
== Etymology ==
This word was made by combining "googol" (10100) + "quadri-" (4) + "-plex" (10n).
== Other names ==
DeepLineMadom calls the number troogolquadriplex, and is equal to 10[3]10[3]10[3]10[3]10[3]100 in DeepLineMadom's Array NotationDeepLineMadom's googology - Numbers I've coined (Retrieved 4 May 2022).
