Bigrand Megahugexul

The Bigrand Megahugexul is equal to ((...((200![200(1)200])![200(1)200])![200(1)200]...)![200(1)200])![200(1)200] (with Grand Megahugexul parentheses), using 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 Latin prefix "bi-" and the number "grand Megahugexul".
