Grand petahyperfaxul

The grand petahyperfaxul is equal to \(a_\text{petahyperfaxul}\), where \(a_n\) = \(a_{n-1}![1]\) and \(a_0 = 200![1]\), 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 the word "grand" and the number "petahyperfaxul".
