The Archimedean Anti-Prisms

The infiniate set of semi-regular anti-prisms. These are regular-based with equilateral trinangular sides. For n ∈ {4,5,6,7,8,...} we obtain a semi-regular anti-prism whose base is a regular n-gon. For n = 3 we obtain the regular octahedron. In these anti-prisms, three equilateral triangles and an n-gon meet at each vertex.
