I think 69 is also a perfect number lol
Its hard going through over a million digits. That must have taken years to find

Awesome. I love number theory. I'm terrible at any math beyond algebra, but it's clear that patterns exist in numbers, bizarre patterns that are way cool as hell.
I think theorists are still trying to find a proof that says there's an infinite number of perfect numbers, but they can't come up with such a proof yet? There's a really nice book that talks about the history behind Fermat's Last Theorem. The book is called "Fermat's Enigma", and it's very easy to read for anyone with no more than a basic understanding of algebra.

Well if there are an infinite amount of numbers then theres an infinite amount of perfect numbers theyre just spaced really far apart. Its just like prime numbers: at first theyre all close together then really far apart
