Deutero-tethratope

Deutero-tethratope (also called tethratope-by-tethratope) is equal to E100#^^#^#*#^^#^#100 using Extended Cascading-E Notation. The term was coined by Sbiis Saibian. The expression should not to be confused with deutero-tethrahecton, which is E100(#^^#^100)*(#^^#^100), which is much smaller than this number.
