Geometric Model by A. Harry Wheeler, Truncated Icosahedron

notes: label: Description
content: 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 twenty-sided icosahedron, one can produce this truncated icosahedron, which has twenty faces that are regular hexagons and twelve that are regular pentagons. 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.

content: This white plastic model of a truncated icosahedron is marked: 11 (/) AVI. Wheeler assigned it the general number 11 and it was number VI of his Archimedean solids.
