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.
== Cartesian coordinates ==
Cartesian coordinates for the vertices of this compound are all the cyclic permutations of
: (0, ±2, ±2τ)
: (±τ−1, ±1, ±(1+τ2))
: (±τ, ±τ2, ±(2τ−1))
where τ = (1+√5)/2 is the golden ratio (sometimes written φ).
