From Wikipedia, the free encyclopedia

Compound of five octahedra
Type Compound and stellation
Polyhedra 5 octahedra
Faces 40 triangles

Dual Compound of five cubes
Symmetry group icosahedral (Ih)

This polyhedron can be seen as either a polyhedral stellation or a compound. This compound was first described by Edmund Hess in 1876.

[edit] As a compound

It can also be seen as a polyhedral compound of five octahedra arranged in icosahedral symmetry (Ih).

It shares the same vertex arrangement as the icosidodecahedron.

[edit] As a stellation

It is the second stellation of the icosahedron, and given as Wenninger model index 23.

It can be constructed by a rhombic triacontahedron with rhombic-based pyramids added to all the faces, as shown by the five colored model image.

The stellation facets for construction are:
