This reminded me of tetration and Knuth's up-arrow notation. It's basically repeated exponentiation.
Searching now, I just learned of tetrofactorial, which is a factorial using tetration operations.
There's also pentation which is repeated tetration.
And there's a whole wiki for it here: googology.fandom.com
It's fun because the numbers are so big it's basically infinity but any of those numbers is still nothing compared to infinity.
