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?

Brian,

"There can be any number of hexagons (including zero)"

Any number? Or is "quantized", and the number of hexagons must follow a pattern/sequence (e.g., 0, 20, ... )
