Thanks to Edwin Clark and Don Reble who were the first to check the squares. Good news: test OK! And thanks to others who asked or were about to ask the file, but I think that new tests are not necessary, the 5 squares being confirmed correct. Christian. -----Message d'origine----- De : math-fun-bounces+cboyer=club-internet.fr@mailman.xmission.com [mailto:math-fun-bounces+cboyer=club-internet.fr@mailman.xmission.com] De la part de Christian Boyer Envoyé : mercredi 16 novembre 2005 19:41 À : 'math-fun' Objet : [math-fun] Need help for some tests I have new multiplicative magic squares of orders 10, 11, 12, 13, 14. I think that they are correct... but because stupid errors are always possible when objects use more than 100 integers, I search an external checking of the 5 examples. Who could check that the squares are correct? Use of distinct integers, good products, checking of broken diagonals for pandiagonal squares. Warning: magic products reaching 10^29. Any help will be appreciated! Send me a direct message, I will send you an Excel file (or a text file if you prefer) with the 5 squares ready to be checked. Thanks!
