content: Wheeler, Albert Harry
notes: label: Description
content: This colorful plastic model is inscriptible in a regular tetrahedron. Six irregular hexahedra, with two parallelograms and four trapezoids for sides, have been cut out along the edges of the regular tetrahedron. This leaves (where edges were) four faces that each have an equilateral triangle at the center and coplanar parallelograms emerging from each vertex of the triangle. Numerous sides are coplanar. A mark on the model reads: 653. Wheeler also identified it as his model M12.
