The grand tethracross is equal to E100#^^##100#2 using Extended Cascading-E Notation.[1] The term was coined by Sbiis Saibian. This number is comparable with Grand Penthrathoth.
Etymology[]
The name of this number is based on the prefix "grand" (which adds #2 at the end of the expression) and the number "tethracross".
