Geometric Model by A. Harry Wheeler, Icosidodecahedron

Description:

This faces of this tan plastic model are twenty equilateral triangles and twelve pentagons. The sides and 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.

The model is marked on a typed paper tag: RS 9. It is marked in ink: IX (/) 14. This model had Wheeler’s number 14 and was number IX of his Archimedean solids.
