No, it's not my phone number, it's much larger than that click here

I have to say it's a bit beyond my processing power as I am the human equivalent of a 386.

The last ten digits are my phone number. How spooky is that?

i always thought graham was the new infinity replacing a google plex as the highest number.

a goole was 1 and a hundred zeros, plex was multipled by itself with no end.

In other words, G is calculated in 64 steps: the first step is to calculate g1 with four up-arrows between 3's; the second step is to calculate g2 with g1 up-arrows between 3's; the third step is to calculate g3 with g2 up-arrows between 3's; and so on, until finally calculating G = g64 with g63 up-arrows between 3's.

Everyone with me so far?

What is Graham's number plus 1?

Thought the answer to everything was 42?

The number will end, but the observable universe is much too small to contain a digital representation of it, so as far as we're concerned it might as well be infinite.

Yikes. That really is a big number. Taken me a while to read and understand it (probably) properly, but it makes me wonder exactly how and why Mr Graham came up with the question.
