This study exposes some statistics concerning palindromic primes.

For every length it gives the total number of existing palindromic primes

as well the smallest and greatest primes for those lengths.

Also in this section, now dispersed over five pages, you'll find a variety of

facts and figures about palindromic primes. Don't look for a logical order. It is

just an amalgamation of randomly gathered curios, puzzles, contributions and

more general information. I hope you like them.
