A flat ball? (Posted on 2004-04-08)

Soccer balls are usually covered with a design based on regular pentagons and hexagons.

How many pentagons/hexagons MUST there be, and why?

Johnson solids

| Comment 20 of 25 |

Although it is true that there is no hexagon and pentagon Johnson solid, this doesn't rule out the possibility of a non-convex shape.

Not that it would make a very good soccer ball.
