What is your favorite prime number besides 13 and 17?

137 or 173!
Its not 13 or 17 :)

Yeah haha I was gonna say 73

I really like 199. Seems like it shouldn't be prime but it is. Also, the primes that multiply together to make a perfect number, like 8191 for instance, are pretty cool. I guess those are the Mersenne primes. I like them a lot, 7, 31, 127(I think), 8191, etc.

There are an infinite number of primes. It's quite elementary to prove so.

Now twin primes on the other hand...
