Hyperfaxul

The hyperfaxul (also called ducenfaxul) is equal to 200!200 or 200![1] using Hyperfactorial Array Notation. In Jonathan Bowers' bracketed operator notation it can be expressed as \(200\{200\}199\{200\}198\{200\}\cdots\{200\}4\{200\}3\{200\}2\). The term was coined by Lawrence Hollom.Lawrence Hollom's large number site
=== Etymology ===
The name of this number is based on prefix "hyper-" and the number "faxul".
