Compound of twelve pentagrammic antiprisms Type Uniform compound Index UC45 Polyhedra 12 pentagrammic antiprisms Faces 120 triangles, 24 pentagrams Edges 240 Vertices 120 Symmetry group icosahedral (Ih) Subgroup restricting to one constituent 5-fold dihedral (D5) This uniform polyhedron compound is a symmetric arrangement of 12 pentagrammic antiprisms, aligned in pairs with the axes of fivefold rotational symmetry of a dodecahedron. It results from composing the two enantiomorphs of the compound of 6 pentagrammic antiprisms.
