Grand Exafaxul

The grand exafaxul is equal to ((...((200!)!)!...)!)!Lawrence Hollom's large numbers site (with exafaxul ()'s) or 200!200!7+1 using Nested Factorial Notation. The term was coined by Lawrence Hollom.
== Etymology ==
The name of this number is based on the word "grand" and the number "exafaxul".
