nonconvex uniform polyhedron
 |
Small snub icosicosidodecahedron
|
A uniform polyhedron of a type
obtained by relaxing the conditions used to produce the Archimedean
solids (which have regular convex faces and identical convex vertices)
to allow both nonconvex faces and vertex types, as in the case of the Kepler-Poinset
solids. The condition that every vertex must be identical, but the faces
need not be, gives rise to 53 nonconvex uniform polyhedra. An example is
the great truncated dodecahedron, obtained by truncating
the corners of the great dodecahedron at a depth which gives regular decagons.
