Usage conditions apply
This colorful plastic model has twelve triangular pieces on each of four sides, for a total of forty-eight pieces. Many of these pieces are coplanar with other pieces. Wheeler described it as a “one-sided polyhedron derived from the regular tetrahedron by passing planes through the edges perpendicular to the opposite edges.” A mark on the model reads: 687. Wheeler also considered it model M72 in his series of models of one-sided polyhedra.
