Geometric Model by R. Anderson, a Student of A. Harry Wheeler, Truncated Octahedron


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 wooden model of a truncated octahedron is marked: 9. It also is signed in pen: R. Anderson (/) March 28, '38. Wheeler assigned his model of the truncated octahedron the general number 9. This example was built by a student.
