- Description
- This model might be seen aas three four-sided oblique pyramids, joined to form a three-legged model. Each pyramid has two black and one tourquois side. The tree bases are also turquoise. However, in this particular version of the model. two black faces of adjacent pyramids are in the same plane. Hence they contribute three, not six, faces to the model. Moreover, The base of a pyramid is in the same plane as two of the turquoise faces of other puramids. Hence the turquise pieces contribute three other faces, for a total of six faces. Wheeler also computes that the model has six vertices and twelve edges. This gives an Euler characteristic of 0, which characterizes a one-sided polyhedron.
- A tag on the object reads: M 11. A mark reads: 652 (/) e=6 (/) k=12 (/) f=6 e-k+f=0.
