Small rhombihexacron
Introduction 3D model of a small rhombihexacronIn geometry, the '''small rhombihexacron''' (or '''small dipteral disdodecahedron''') is the dual of the small rhombihexahedron. It is visually identical to the small hexacronic icositetrahedron. Its faces are antiparallelograms formed by pairs of coplanar triangles.
Proportions Each antiparallelogram has two angles of  and two angles of . The diagonals of each antiparallelogram  intersect at an angle of . The dihedral angle equals . The ratio between the lengths of the long edges and the short ones equals .
