Medial hexagonal hexecontahedron
Introduction 3D model of a medial hexagonal hexecontahedronIn geometry, the '''medial hexagonal hexecontahedron''' (or '''midly dentoid ditriacontahedron''') is a nonconvex isohedral polyhedron. It is the dual of the uniform snub icosidodecadodecahedron.
Proportions The faces of the medial hexagonal hexecontahedron are irregular nonconvex hexagons. Denote the golden ratio by , and let  be the real zero of the polynomial . The number  can be written as , where  is the plastic ratio. Then each face has four equal angles of , one of  and one of . Each face has two long edges, two of medium length and two short ones. If the medium edges have length , the long ones have length  and the short ones . The dihedral angle equals .
