- Description
- The underlying structure of this plastic model is a rhombic dodecahedron with a four-sided slanting pyramid erected on each face. The triangular sides of the pyramids are not equilateral, but are congruent. The triangles are colored blue, turquoise, and black (sixteen of each). Each triangle is coplanar with one other triangle of the same color, reducing the number of faces to 24. A paper tag on the model reads: M 6. Another mark reads: 647. A third mark reads: e=18 (/) k=48 (/) f=24 (1) e-k+f= -6. Here e is the number of vertices (Wheeler used the German ecken), k is the number of edges (kanten in German) and f is the number of faces. Wheeler classified the model as M6 in his one-sided polyhedra.
