Giggol in zeroes

The giggol is equal to $$\lbrace10,100,2\rbrace$$ in BEAF, or 10 tetrated to 100.[1] Thus, it's 10010 = 1010...1010, where there are 100 tens. The term was coined by Jonathan Bowers.

This number is also called hectalogue by Sbiis Saibian, and it's equal to E1#100 in Hyper-E Notation.[2][3]

It was the last number on Robert Munafo's Notable Properties of Specific Numbers.[4] In February 2013, it was superseded by mega.

Username5243 calls this number doogol, and it's equal to 10[2]100 in Username5243's Array Notation.[5]
