 In general, snubs have chiral symmetry with two forms, with clockwise or counterclockwise orientations.By Kepler's names, a snub can be seen as an expansion of a regular polyhedron, with the faces moved apart, and twists on their centers, adding new polygons centered on the original vertices, and pairs of triangles fitting between the original edges.The terminology was generalized by Coxeter, with a slightly different definition, for a wider set of uniform polytopes.
