0 Guest Posted June 13, 2009 Report Share Posted June 13, 2009 I'm having trouble posting this. Here's the basic text: The chessboard problem set me thinking. One of my favourite problems in maths is the pentomino problem - getting all the different shapes made up of 5 squares into a 10 by 6 rectangle. I was given a plastic pentomino puzzle as a teenager, and I still have it. There are a lot of solutions - just how many I’m not sure. Anyway, a lot has been written about pentominos, but I have never seen this one.…. Take a chess board and cut out the middle 4 squares, leaving 60 squares. Which of the 12 different pentominos can you tessellate to fill the board? I have done some good diagrams, but I don't know how to put them on this forum posting. Help, anyone?

If they are pictures (such as JPEG, GIF, etc.) you can upload them to ImageShack, and then after uploading them, using the "direct link" URL, you can then insert them into posts via the "Insert Image" tool, when writing your posts/threads. Hope that helps, random7 Quote Link to comment Share on other sites More sharing options...
