content: Cutting off the vertices of a polyhedron with regular polygons as faces may create another polyhedron which may also have faces that are regular polygons. When 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.
label: Description
content: This cut, folded, and glued paper model has a total of sixty-two faces, twenty regular hexagons, thirty squares, and twelve regular decagons.. A mark reads: A. Harry Wheeler (/) Nov. 5, 1931. Another mark reads: Pat. 1292188. A third mark reads: 19. A fourth mark reads: XIV. Wheeler considered it the fourteenth Archimedean solid and gave it his more general number 19.
