In this well-filled website you'll find a variety of facts and figures 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! | |||||||||||
