The rhodomesohedron is the mesotruncate of the dodecahedron and icosahedron. It is also called the icosidodecahedron, which is an interesting name as it represents both the number of faces in the polyhedron (icosidodeca = 32) and also the combination of the two regular polytopes that can be rectified to form it (icosahedron + dodecahedron).
