[math-fun] A different 7-11 puzzle ... dividing a 37x37 square

In other news, RSA576 has been factored. Erich Friedman/John Hoffman has a different 7-11 puzzle that I think is very nice. Divide a 37x37 square into smaller squares ranging in size from 7x7 to 11x11. I believe the answer is unique. The problem is discussed at http://www.stetson.edu/~efriedma/mathmagic/1298.html I also mention it in my woefully obsolete Square Packing column. In just 4 days, there have been 10 discoveries in square packing. That's good, though! I'll be updating that column soon. http://maa.org/editorial/mathgames/mathgames_12_01_03.html The solution is at http://www.stetson.edu/~efriedma/mathmagic/1298/f37.gif --Ed Pegg Jr.
