Bigrand megahyperfaxul is equal to \(a_\text{grand megahyperfaxul}\), where \(a_n\) = \(a_{n-1}![1]\) and \(a_0 = 200![1]\), using Hyperfactorial Array Notation. The term was coined by Lawrence Hollom.[1]

Etymology

The name of this number is based on Latin prefix "bi-" and the number "grand megahyperfaxul".
