check out this page http://mathworld.wolfram.com/PalindromicPrime.html

actually....hmm...it's displaying different bases, so that's probably confusing

I coudn't find anything on either page

jim_thompson5910 · Answer

and if you look at the sequence of Palindromic primes, you get this

	2, 3, 5, 7, 11, 101, 131, 151, 181, 191, 313, 353, 373, 383, 727, 757, 787, 797, 919, 929, 10301, 10501

but nowhere in this list is a 4 digit prime number

so it looks like it doesn't exist

Thanks anyways!

jim_thompson5910 · Answer

it goes from 929 to 10301, so hopefully there isn't a typo

if not, then it's safe to say a 4 digit palindromic prime is not possible

oh found this too http://en.wikipedia.org/wiki/Palindromic_prime on this page it says "Except for 11, all palindromic primes have an odd number of digits"
