[math-fun] Multiplicative squares

Website updated this morning! Go to <http://www.multimagie.com/indexengl.htm> www.multimagie.com/indexengl.htm: in the News of October 2005, there is a new page on multiplicative squares, including the results sent past week. The 10 first magic products should be sufficient for the site, but I send to Neil the 30 first terms of each order (3x3, 4x4, and 5x5) for his EIS. You will see that I've finally found a paper -published in 1983- already proving that the minimum product for 3x3 and 4x4 squares are 216 and 5040. But, Rich, your nice and short proof on 216 is in my new page! Christian.
