The boggol is equal to $$\{10,10,100,6\}$$ in BEAF.[1] The term was coined by Chris Bird. Jonathan Bowers jokingly says about this number, "Boggles the mind, doesn't it?"

Username5243 calls this number Hexukiloogol (formerly Hexumegoogol), and it's equal to 10[0,6]100 in Username5243's Array Notation.[2]

## Etymology

The name of the number is based on the Latin prefix "bi-" and the number "goggol".
