Goobol

The goobol is equal to \(\lbrace10,100 (1) 2\rbrace = \{\underbrace{10,10 \ldots 10,10}_{100}\} = 100 \& 10\) in BEAF. The term was coined by Jonathan Bowers.
Goobol is comparable to Saibian's godgahlah.
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}
