The tetrakis cuboctahedron is a convex polyhedron with 32 triangular faces, 48 edges, and 18 vertices. It a dual of the truncated rhombic dodecahedron.

Its name comes from a topological construction from the cuboctahedron with the kis operator applied to the square faces. In this construction, all the vertices are assumed to be the same distance from the center, while in general icosahedral symmetry can be maintained the 6 order-4 vertices at a different distance from the center as the other 12.

Related polyhedra

It can also be topologically constructed from the octahedron, dividing each triangular face into 4 triangles by adding mid-edge vertices (An ortho operation. From this construction, all 80 triangles will be equilateral.

This polyhedron can be confused with a slightly smaller Catalan solid, the tetrakis hexahedron, which has only 24 triangles, 32 edges, and 14 vertices.
