Summary

Description
English: The helix contains 8 regular tetrahedra, 8 vertices, and 24 edges. When it is bent into a ring (in the fourth dimension), the two triangular faces at each end of the helix are the same face. The helix is bounded by three 8-edge octagrams of different colors. The orange and yellow edges are two 4-edge segments of the same 8-edge octagram.
