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?
Solution has not concluded yet. I has to modify a little bit. As the time constraint, you should view the picture in the comment that I sent just now that the process is still on process tomorrow.
Thanks.
Solution- I still have to modify the picture
