Medial icosacronic hexecontahedron
In geometry, the medial icosacronic hexecontahedron 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.
