It depicts a nonconvex regular polyhedron known as the small stellated dodecahedron. This convex polyhedron is topologically similar to the concave stellated octahedron. Truncating edges down to points produces the great icosidodecahedron as a rectified great stellated dodecahedron. A truncation process applied to the great stellated dodecahedron produces a series of uniform polyhedra. It shares its vertex arrangement with the great stellated truncated dodecahedron. The stellated octahedron is the only stellation of the octahedron. Both tetrahedral positions make the compound stellated octahedron. The compound figure comprising two such dual tetrahedra form a stellated octahedron or stella octangula. The first stellation, often simply called the stellated rhombic dodecahedron, is well known. Adding tetrahedra to all 8 faces creates the stellated octahedron. A marble tarsia in the floor of St. Mark's Basilica, Venice, depicts a stellated dodecahedron. It also shares the same edge arrangement as the small stellated dodecahedron. Magnus Wenninger creates colourful stellated polyhedra, originally as models for teaching. For example, in "Gravitation", animals climb around a stellated dodecahedron. John Conway devised a terminology for stellated polygons, polyhedra and polychora (Coxeter 1974).
