In 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 .
