The pentadecal is equal to {10,10,10,10,10} (10 uzodecodecated to 10) in BEAF[1] or 10 bi-rowexponentiated to the fifth, using the array of operator. The term was coined by Jonathan Bowers.

Pentadecal is comparable to \(f_{\omega^3}(10)\) in the fast-growing hierarchy.


The name of this number is based on the words "penta-" (greek: five) and "decal-" (greek: ten), meaning that there are 5 10's in the array.
