Tethrathothitoth

Tethrathothitoth is equal to E100#^#^...#^#^#100 (101 #'s) = E100#^^#101 in Extended Cascading-E Notation. The term was coined by Sbiis Saibian. It is comparable to and larger than goppatoth.
SeveralLegend9998 coined ascended grangol for this number, and it's equal to E100(E[#]#{#}#)100 = E100(E[#]#{#}100)100 in Ascending-E Notation.
