Actually, Graham's number is now considered pretty small by mathematicians. For example, TREE(3) is so big that it makes Graham's number look like pretty much like zero in comparison. The interesting thing about the TREE function is that it grows so rapidly eg.

Actually, Graham's number is now considered pretty small by mathematicians. For example, TREE(3) is so big that it makes Graham's number look like pretty much like zero in comparison. The interesting thing about the TREE function is that it grows so rapidly eg.

TREE(1) = 1

TREE(2) = 3

TREE(3) = something insanely big!
