Description
Cutting off the vertices of a regular polyhedron creates another polyhedron which may also have faces that are regular polygons. If one cuts off the vertices of a regular octahedron, one can produce this truncated octahedron, which has six faces that are squares and eight that are regular hexagons. The solid angles of the figure are equal, and it is called a semi-regular solid. The ancient Greek mathematician Archimedes enumerated the eighteen regular and semi-regular solids, and they are known as Archimedean solids in his honor.
This tan paper model of a truncated octahedron is marked: RS4 It also is marked: 9/21 (/) RS4. Wheeler assigned it the general number 9 and it was number IV (or 4) of his Archimedean solids.
