Medial icosacronic hexecontahedron
Introduction 3D model of a medial icosacronic hexecontahedronIn geometry, the '''medial icosacronic hexecontahedron''' (or '''midly sagittal ditriacontahedron''') is a nonconvex isohedral polyhedron. It is the dual of the uniform icosidodecadodecahedron. Its faces are darts. Part of each dart lies inside the solid, hence is invisible in solid models.
Proportions Faces  have two angles of , one of  and one of . Its dihedral angles equal . The ratio between the lengths of the long and short edges is .
