Usage conditions apply
.This plastic model is inscriptible in a regular tetrahedron. It has six rectangular pieces, each of which is coplanar with four small triangles of the same color. It also has four pink pieces in the shape of an equilateral triangle with a triangular hole cut out of the center. Finally, four blue-green triangles are near the vertices of what would be an inscribing tetrahedron. A tag on the model reads: 660. A mark on the model also reads: 660.
The figures at the four corners of the model are in roughly the shape of faceted octahedra, and Wheeler referred to it as an “octahedral” polyhedron.
