The Truncated Dodecahedron
A semi-regular polyhedron with two decagons and a triangle meeting at each vetex.
The truncated dodecahedron 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.
