Grand gigahexofaxul

The grand gigahexofaxul is equal to (((...(((200!4)!4)!4)!4)...)!4 (with gigahexofaxul ()'s) in Hyperfactorial array notation. The term was coined by Lawrence Hollom.Lawrence Hollom's large number site
=== Etymology ===
The name of this number is based on the word "grand" and the number "gigahexofaxul".
