That reminds me of something I did over 50 years ago when I was still at school. By cutting a series of binary-coded holes and slots along the edge of ordinary playing cards, it was possible to sort the deck using a knitting needle. I learned how to do this from a book called "The Gentle Art of Mathematics", by Dan Pedoe, published in 1958. I still have that book, and somewhere, hidden away in a box, I think I still have the deck of cards. Good luck to Tony! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
