Product Description
A compound of 20 cubes, with two cube vertices at each vertex. This non-convex polyhedron is related to the Compound of 20 Octahedra because the cubes used are in the 'dual' position (with vertices at the centers of the faces of the octahedra, and edges perpendicular to the octahedra). It has 140 vertices and 240 edges (counting the cube edges as 'edges').
