Biggol

Biggol is equal to \(\{10,10,100,2\}\) or \(10\{\{100\}\}\)10 in BEAF. It was coined by Chris Bird (along with the baggol, beegol, bigol, boggol, and bagol) to compare the boogol with the giggol, gaggol, etc.
Username5243 calls this number Dukiloogol (formerly Dumegoogol), and it's equal to \(10[0,2]100\) in Username5243's Array Notation.
Biggol can be computed in the following process:
* \(a_1 = 10\)
* \(a_2 = \{10,10,99,2\}\)
* \(a_3 = \{10,a_2,99,2\}\)
* \(a_4 = \{10,a_3,99,2\}\)
* etc.
* Biggol is equal to \(a_{10}\).
== Etymology ==
The name of the number is based on Latin prefix "bi-" and the number "giggol".
