I want to divide the surface of a donut into as many different regions as possible. The regions can be any shape, as long as they are each in one piece. Each region must touch each of the other regions (touching on a corner doesn't count). How many regions can I make?
Refer to the drawing as shown on the date, 25/4/05, time: 13:14:18:00, Subject: Solution is on process-please don't open. I have completed the set to prove to everyone that numerous cuttings are possible so as to have numerous regions.
Easy and simply ways.
