Description
This clear plastic model has a tetrahedron on the inside, without a base. The three sides have identical pentahedra attached to them. One side of each pentahedron is a trapezoid on the side of the tetrahedron, a second is a horizontal trapezoid parallel to the plane of the missing base, and two sides are triangles in the plane of adjacent sides of the underlying tetrahedron. Each pentahedron also has a trapezoid on the outside that begins at the base of the tetrahedron and slopes outward. A small equilateral triangle inside the underlying tetrahedron joins the horizontal trapezoids. A mark on the model reads: 680. Wheeler also called the model M39 in his list of one-sided polyhedra.
