The Truncated Icosahedron
The truncated icosahedron is one of the thirteen archimedian solids. It can be created by slicing suitable sections off the vertices of either a dodecahedron or an icosahedron and thus may be inscribed in either solid.

- `e/rho = (sqrt(5)-1)/3`
- `e/R = sqrt((58-18sqrt(5))/109)`
- `e/(e_12) = (7+5sqrt(5))/38`
- `e/(e_20) = 1/3`
