Compound of twelve pentagonal prismsTypeUniform compoundIndexUC35Polyhedra12 pentagonal prismsFaces24 pentagons, 60 squaresEdges180Vertices60Symmetry groupicosahedral (Ih)Subgroup restricting to one constituent5-fold dihedral (D5) This uniform polyhedron compound is a symmetric arrangement of 12 pentagonal prisms, aligned in pairs with the axes of fivefold rotational symmetry of a dodecahedron.
It results from composing the two enantiomorphs of the compound of six pentagonal prisms. In doing so, the vertices of the two enantiomorphs coincide, with the result that the full compound has two pentagonal prisms incident on each of its vertices.
