Pentacthultope

Visual representation of pentacthultope

The pentacthultope (also called pentacthulhecton) is equal to E100#^^^#^#100 (the expression is not to be confused with penthrathoth) = E100#^^^###...###100 (with 100 #'s on the right of ^^^) in Extended Cascading-E Notation.[1] The term was coined by Sbiis Saibian.

Etymology[]

The name "pentacthultope" is based on the number pentacthulhum and the root "tope" from "polytope".

The name "pentacthulhecton" is based on the number pentacthulhum and the root "hecton", meaning a 100-dimensional figure.
