[ April 2012 ]

The newest palindromic prime record is from Darren Bedwell
10²⁹⁰²⁵³ - 2 * 10¹⁴⁵¹²⁶ - 1
(290253 digits)
Written out, it's 145126 nines, a seven, and 145126 more nines
and is therefore a PWP or a Palindromic Wing Prime.

The record Palindromic Primes

In this well-filled website you'll find a variety of facts and figures
about topics from the World!Of Numbers . Don't look for a logical
order. It is an amalgamation of randomly gathered numbers, curios,
puzzles, palindromes, primes, gems, your much valued contributions
and more general information. For old time's sake my material,
split up in manageable chuncks, is presented on a silver plate
(of course I'm refering here to the background color!)
just as the various menu's you are familiar with and which are
always at your disposal further on. Enjoy!
