To add to what Alemagno said: If we call your number N, then it isn't difficult to prove that: 3G64 < N < 33 G64  Remember, Graham's Number is just a very big power tower of 3's: G64 = 3↑↑K (for some very big K) So: 3↑↑(K+1) < N < 3↑↑(K+2) This is what Alemagno meant, when he said that your "upgrade" of Graham's Number is like adding 1 to a million (and K is much much much bigger than a million. In fact, K is very close to Graham's Number itself).
