What is the shortest distance between two opposite points (two vertices separated by 2R) in the surface of a regular icosahedron? The regular icosahedron's edges are 1ft in length.

Thanks for the link: 2R=1.902113033 based on how I read its formulas. This agrees with Tristan's figure in his comment below.
