Compound of two snub dodecahedra
Type	Uniform compound
Index	UC69
Polyhedra	2 snub dodecahedra

Vertices	120
Symmetry group	icosahedral (Ih)
Subgroup restricting to one constituent	chiral icosahedral (I)

This uniform polyhedron compound is a composition of the 2 enantiomers of the snub dodecahedron.

The vertex arrangement of this compound is shared by a convex nonuniform truncated icosidodecahedron, with rectangular faces, alongside irregular hexagons and decagons, each alternating two different edge lengths.
