Not to be confused with Pentacthultope by Sbiis Saibian, which is written as the same expression, but represents a different value.

Penthrathoth is equal to E100#^^#^^#...#^^#^^#^#100 (100 ^^'s) = E100#^^^#^#100 in Nested Cascading-E Notation.[1] The term was coined by Aarex Tiaokhiao. Penthrathoth is comparable to Cookie Fonster's boppatoth and Saibian's tethracross.

Etymology[]

The name of the number is based on the Egyptian God of mathemathics Thoth and the word "pentation".
