It is composed of a handfull of > pentagons surrounded by hexagons. > rick @ oliven From a discussion I've had with Roger Noe: If the pentagons and hexagons were flat, the ball would favor the pentagons, because if on a pentagon face vs. a hexagon face: 1. The Center of Gravity is closer to the surface 2. The angular movement needed to upset the die is greater. When the ball becomes a sphere, these differences are removed. -- The Ice Floe of Larry Bickford {amd,decwrl,sun,idi,ittvax}!qubix!lab You can't settle the issue until you've settled how to settle the issue.
