Ennadecal

Ennadecal is equal to {10,10,10,10,10,10,10,10,10} in BEAF or 9 & 10, using the array of operator. The term was coined by Jonathan Bowers.
Ennadecal is comparable to \(f_{\omega^7}(10)\) in the fast-growing hierarchy.
==Etymology==
The name of this number is based on the words "enna-" (Greek for nine) and "decal-" (Greek for ten), meaning that there are 9 10's in the array.
