A chamfered octahedron, which could also know known as a tritruncated rhombic dodecahedron, is a polyhedron obtained by chamfering a
regular octahedron. The illustration above
shows increasing amounts of chamfering applied to the regular
octahedron.

An equilateral chamfered octahedron may be constructed by appropriate choice of the edge length ratio for chamfering. The unit equilateral chamfered octahedron has surface area and volume
