Googolplexichime is equal to 10101,000 = 1010103, = E1,000#2 = EE1,000 using Hyper-E notation.[1] The name was coined by Sbiis Saibian. It is equal to 1 followed by a googolchime (ten duotrigintatrecentillion) zeros. It is 101000+1 digits long.

Username5243 calls this number goomolplex, and it's equal to 10[1]10[1]1,000 in Username5243's Array Notation.[2]

Written out in scientific notation of googolplexichime is:

Writing down the full decimal expansion would take 10994 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).

## Etymology

The name comes from the 2 parts, which are "googolplex" and the suffix "-chime", which mean, 1010100 and the function that multiplies base value by 10.
