World!Of Palindromic Primes
Introduction
Palindromic Primes are primes that read the same 
left to right (forwards) as from the right to left (backwards)
Here are a few random examples : 3, 131, 71317, 134757431This study exposes some statistics concerning palindromic primes.For every length it gives the total number of existing palindromic primesas well the smallest and greatest primes for those lengths.Also in this section, now dispersed over five pages, you'll find a variety offacts and figures about palindromic primes. Don't look for a logical order. It isjust an amalgamation of randomly gathered curios, puzzles, contributions andmore general information. I hope you like them.Enjoy![ December 9, 2002 ]Did You Know !The string 9136319 was found at position 9128219 counting fromthe first digit after the decimal point of 
. The 3. is not counted.Moreover both numbers are two consecutive palprimes !Dropping the left 91 from the two numbers reveals two other primes28219 and 36319, as well as the combination 91_363_282_19 !
