Geometric Model by A. Harry Wheeler, First Stellation of the Icosahedron or Trakis Icosahedron


This is the simplest stellation of a regular icosahedron. Each of the equilateral triangles is replaced by a three-sided pyramid, to give a twenty-pointed star. It is called both the first stellation of an icosahedron and the triakis icosahedron. This tan paper example is cut and folded. A paper tag reads: 363. Another mark reads: May 30 - 1919.
