Pentadecal

The pentadecal is equal to {10,10,10,10,10} (10 uzodecodecated to 10) in BEAF or 5 & 10, using the array of operator. The term was coined by Jonathan Bowers.
== Etymology ==
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.
