The goobol is equal to \(\lbrace10,100 (1) 2\rbrace = \{\underbrace{10,10 \ldots 10,10}_{100}\} = 100 \& 10\) in BEAF.[1] The term was coined by Jonathan Bowers.
Goobol is comparable to Saibian's godgahlah, and could be described as 100 arguments with all numbers in its arguments being 10.
It is also expanded to:
{10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10}
SeveralLegend9998 calls this number boodol, and it's equal to 10(100)10 in Hyperdimensional Array Notation.[2]
