Small rhombihexacron

In 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.

Each antiparallelogram has two angles of

arccos ⁡ (

arccos ⁡ ( −

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
