Grand petatetrofaxul

The grand petatetrofaxul is equal to (((...(((200!2)!2)!2)!2)...)!2 (with petatetrofaxul ()'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 "petatetrofaxul".
