Description
The inside of this cut and glued plastic model is a triangular dipyramid with six equilateral triangles as sides. Around the middle are three congruent irregular octahedron. Each has two rectangular and two trapezoidal sides, as well as two small triangles at each end. The shorter side of each trapezoid is an edge of the bipyramid. The small triangles create four-sided facets at three corners of the model. Each small triangle is coplanar with another small triangle, a triangle of the bipyramid, and a trapezoid of an irregular octahedron. A mark on the model reads: 682. Wheeler also gave this model his number M41.
