This uniform polyhedron compound is a symmetric arrangement of 12 pentagonal antiprisms. It can be constructed by inscribing one pair of pentagonal antiprisms within an icosahedron, in each of the six possible ways, and then rotating each by an equal and opposite angle θ.
When θ is 36 degrees, the antiprisms coincide in pairs to yield the compound of six pentagonal antiprisms.
This compound shares its vertices with the compound of twelve pentagrammic crossed antiprisms with rotational freedom.
