[math-fun] January update of multimagie.com

The January update of www.multimagie.com/indexengl.htm is now online: - With a new page on the hidden link between Sudokus and bimagic squares, as announced in this forum in November. - With latest results on multiplicative squares from 3x3 to 17x17, including 8x8 and 9x9 additive-multiplicative squares. Thanks again to Don, Edwin and Günter for their checking of the biggest squares. An Excel file can be downloaded including these squares. - And other news (highly multimagic squares, ...) I wish you a happy new year 2006. Christian.
