is a composition of 5 small stellated dodecahedra, in the same arrangement as in the compound of 5 icosahedra
Compound of five icosahedra
This uniform polyhedron compound is a composition of 5 icosahedra. It has icosahedral symmetry Ih.The triangles in this compound decompose into two orbits under action of the symmetry group: 40 of the triangles lie in coplanar pairs in icosahedral planes, while the other 60 lie in unique planes.-...
