Tethratopocross (formerly known as tethratoposquaror) is equal to E100#^^(#^#*##)100 in Extended Cascading-E Notation.[1] The term was coined by Sbiis Saibian. This number belongs to the tethratope regiment.
This number is not to be confused with tethomath, which is defined using the same expression but using different notation, which is Nested Cascading-E Notation.
