Small hexacronic icositetrahedron

In geometry, the small hexacronic icositetrahedron is the dual of the small cubicuboctahedron.

It is visually identical to the small rhombihexacron.

A part of each dart lies inside the solid, hence is invisible in solid models.

Its faces are darts, having two angles of

arccos ⁡ (

) ≈ 16.842

arccos ⁡ (

− arccos ⁡ ( −

Its dihedral angles equal

The ratio between the lengths of the long edges and the short ones equals
