Tethratope

Tethratope (also called tethrahecton and tethratopos) is equal to E100#^^#^#100 = E100#^^###...###100 (100 #'s on the right of ^^) in Extended Cascading-E Notation. The term was coined by Sbiis Saibian. Tethratope is comparable to Bowers' weak bound humongulus. This number belongs to the tethratope regiment.
== Etymology ==
The name "tethratope" is based on the number tethrathoth and the word "tope", since the general term for a polyhedron, polychoron etc. is a polytope.
The name "tethrahecton" is based on the number tethrathoth and the root "hecton", meaning a 100-dimensional figure.
