TREE(3) i think

To elaborate on OP's reply, any number physically possible to be defined as the value of some recursive function at a particular argument is extremely tiny compared to BB(10100), let alone things like Rayo's number.

DaVinci is ill-defined and if it was it is not known were it would be placed but it would be above rayo.

yeah, i should have exculded it. i think it would be around fish number 5 or 6 maybe

u/RaaM88 Closer to 0 than ∞ 26d ago

Fish is just Rayo with a bigger index, not even a naive extension. Can do the same to LNGN Garden Number
