Web2. You will find that there are twelve pentagons - briefly: The graph will be planar, because you can take any face of the ball and stretch it to flatten out the sphere. The Euler formula V + F = E + 2 links the number of vertices, faces and edges. Three edges at a vertex means 3 V = 2 E. Also counting the edges of the faces 5 P + 6 H = 2 E and ...

The animation (4.9MB, Quicktime .mov) shows how to transform a soccer ball with slits along two of its edges into a torus. Any two edges of equal type can be chosen. The two edges used were chosen to obtain a not-too-large stretching/compression of the pentagons/hexagons on the resulting torus. northern powergrid postal address
