High Quality Content by WIKIPEDIA articles! In geometry, an alternation (also called partial truncation, snub or snubification) is an operation on a polyhedron or tiling that birectifies alternate vertices. Only even-sided polyhedra can be alternated, for example the zonohedra. Every 2n-sided face becomes n-sided. Square faces disappear into new edges. An alternation of a regular polyhedron or tiling is sometimes labeled by the regular form, prefixed by an h, standing for half. For example h{4,3} is an alternated cube (creating a tetrahedron), and h{4,4} is an alternated square tiling (still a square tiling).
