Hexadecal

The hexadecal is equal to \(\{10,10,10,10,10,10\}\) in BEAF or 6 & 10, using the array of operator. The term was coined by Jonathan Bowers.
Hexadecal is comparable to \(f_{\omega^4}(10)\) in the fast-growing hierarchy.
== Etymology ==
The name of this number is based on the words "hexa-" (greek: six) and "decal-" (greek: ten), meaning that there are 6 10's in the array.
