In geometry, this polyhedron can be seen as either a polyhedral stellation or a compound.

As a compound[edit]

It can be seen as the compound of an icosahedron and dodecahedron. It is one of four compounds constructed from a Platonic solid or Kepler-Poinsot solid, and its dual.

It has icosahedral symmetry (Ih) and the same vertex arrangement as a rhombic triacontahedron.

As a stellation[edit]

This polyhedron is the first stellation of the icosidodecahedron, and given as Wenninger model index 47.

The stellation facets for construction are:

In popular culture[edit]

In the film Tron (1982), the character Bit took this shape when not speaking.
