Hi I remember there being a site that has interesting information about almost every smaller number even larger ones. It would say if it is a prime or more obscure information.

Wikipedia has most of that information.

Yeah e.g. for numbers in the 700s it has some information but I thought I remembered a site that had more information about random highish numbers like that.

If you’re willing to buy a book (remember books, those paper and ink things?), there’s *The Penguin Dictionary of Curious and Interesting Numbers* by David Wells which has everything you’re interested in.

It’s a good site

I have several books along these lines, including

Number Freak: From 1 to 200- The Hidden Language of Numbers Revealed

The Kingdom of Infinite Number: A Field Guide

Adam Spencer’s Book of Numbers: A Bizarre and Hilarious Journey from 1 to 100

*The Penguin Dictionary of Curious and Interesting Numbers* is much more thorough than any of those books. It has entries on over a thousand numbers. It has entries not just on integers but on fractions, irrational numbers, and transcendental numbers.

I bought this book when it came out, and have been fascinated by it for years. You beat me to it.

The same guy also came out with the *Penguin Dictionary of Curious and Interesting Geometry*, which I also highly recommend.

And I see that I was beat to the punch by poster #2.

There’s also the site “What’s Special About This Number?”, http://www2.stetson.edu/~efriedma/numbers.html

Do these various sources being cited also include metaphysical facts about numbers? Like, for example, “1” being the loneliest number?

This might be the page I found originally:

It has information about a lot of numbers - though the information is has something to do with prime numbers.
