Googol-ex-grand tethrathoth

The googol-ex-grand tethrathoth is equal to E100#^^#100#(1+E100) in Extended Cascading-E Notation. The term was coined by Sbiis Saibian.
== Etymology ==
The name of this number is based on the number googol and the number "grand tethrathoth".
== Approximations ==
Notation 	Approximation
BEAF 	\(\{100,\text{googol}+2,2(X\uparrow\uparrow X)2\}\)Using particular notation \(\{a,b (A) 2\} = A \&\ a\) with prime b.
