List of the site's news added January 3rd, 2006

• Do you know that there is a link between Sudokus and bimagic squares?
• Updated records table with highly multimagic squares: heptamagic, octamagic, and more... Independant works of Pierre Tougne (France), Pan Fengchu (China), Harm Derksen / Christian Eggermont / Arno van den Essen (USA/Netherlands), and Jaroslaw Wroblewski (Poland)
• New page on the magic squares of cubes, excerpt from the article Some Notes on the Magic Squares of Squares Problem published in The Mathematical Intelligencer.
  ??!!?? With two open problems on magic squares of cubes
• Updated table summarizing very new results on multiplicative magic squares, and three new pages on bigger orders:
• Discovery of the smallest multiplicative squares of order 6 and 7
• Discovery of the smallest multiplicative squares of order 8 and 9, including results of Luke Pebody, England, and my new additive-multiplicative magic squares better than the previously known squares
• Smallest known multiplicative squares of orders 10, 11, 12,... 17. Thanks to Edwin Clark, USA, Don Reble, Canada, and Günter Stertenbrink, Germany, for their checkings of my big squares
• ??!!?? Open problems on multiplicative magic squares. Who will solve some of them?
• New nearly bimagic square of order 13 and of order 14, by Jacques Guéron, France.
• Such numbers were considered as impossible to compute only some months ago! Walter Trump, Germany, using a method invented by Lorenz Schlangen, computed:
• number of bimagic series for squares of order 17, very close to the approximated value previously estimated
• numbers of bimagic series for cubes of order 9 and 10

• In other sites:
