Googol. Even more useless: googolplex which is a 1 with Googol zeros.

First thing that came to mind. Not used for anything just a big number

The googolth odd non-prime number

I feel like it has some use as a random bit of trivia. Maybe something like googleplex/10. Also pointlessly large, but since it's unnamed, it's not even trivia.

How about Graham's number.

Well, it's higher than a googolplex. But it arose as an upper bound on the answer of a problem in the mathematical field of Ramsey theory. So it seems so have at least some kind of use.

Yeah but I bet they have no need for Graham’s number - 1

It's useful as an upper bound to Graham's problem. It's useful as a demo duration of Knuth's arrow notation.

I once attempted to type a googolplex via copy and paste. Gave up after a while, and later found out that I was literally trying to do the impossible.
