Subject: J.J.Sylvester's puzzle
Date: Tue, 9 Dec 1997 22:23:51 -0800 (PST)
From: curranac@bc.edu

I have a puzzle here that has bothered me for some time now and I was wondering if you could help me. If there are 9 coins arranged in a box formation. That is 8 rows of three: the three horizontal rows, the three vertical rows and the two diagonal rows. They then have to be rearanged into 10 rows of 3. I have tried for about three days and I am fed up and I just need to know what the configuration is. I am just desperate. IF you can help me thanks if not i will be tortured for ever.
