Cutting off the vertices of a polyhedron may create another polyhedron which has faces that are regular polygons. When 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 cut and glued tan plastic model has a total of twenty-six faces, including twelve squares, eight regular hexagons, and six regular octagons. Wheeler numbered it XIII among the Archimedean solids and 18 in his general numbering scheme. A mark on it reads: XIII (/) 18. Another mark reads: RS 13.
