Googolplexigong

Googolplexigong is equal to E100,000#2 = EE100,000 = 1010100,000 = 1010105, using Hyper-E NotationHyper-E Notation - Large Numbers by Sbiis SaibianSbiis Saibian's Ultimate Large Numbers List. It is equal to one followed by a googolgong (ten tremyritrimilliduotrigintatrecentillion) zeros. It is 10100,000+1 digits long.
Username5243 calls this number gooqnolduplex, and it's equal to 10[1]10[1]10[1]5 in Username5243's Array Notation.Part 1 - My Large Numbers
Writing down the full decimal expansion would take 1099,994 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
