# Snub

**Snub** has several related meanings in the study of polytopes, especially uniform polytopes. It is primarily seen as a polytope operation where a rank-*n* polytope is expanded by the insertion of (*n* - 1)-simplices at its ridges. The best-known examples are the snub cube, produced by applying this operation to a cube or octahedron, and the snub dodecahedron, made from a dodecahedron or icosahedron. The inserted simplices are also called "snub," such as "snub triangles" in the previous examples.

The snub disphenoid applies the snub operation to a tetrahedron but only to some of its edges.
