The googolplexibyte is equal to 88100 = 8^100#2 = 23*2300 ≒ 101.840×1090using Hyper-E notation.[1] The name was coined by Sbiis Saibian.

Username5243 calls this number Octal-Googolplex, and it's equal to 8[1]8[1]100 in Username5243's Array Notation.[2]

Aarex Tiaokhiao calls this number octal-googolplex.[3]

## Etymology

• (for googolplexibyte) The 2 parts of the name, "googolplex" and the suffix "-byte" mean 1010100 and base 8 (octal). So the full name indicates the content of the number.
• (for octal-googolplex) The 2 parts of the name, the prefix "octal" and "googolplex" mean octal and 1010100. So the full name indicates the content of the number.
