Rhombicosidodecahedron

Properties of the rhombicodidodecahedron: Number of faces, edges and dihedral angle measure

The rhombicosidodecahedron is created by either truncating (cutting off) the dodecahedron one half of the way into each side 
or by truncating the icosahedron one half of the way into each side
