A rhombicuboctahedron is a uniform three-dimensional polyhedron that can be constructed by cantellating a cube or octahedron As a cantellated octahedron, it has the same symmetry group as the octahedron, namely octahedral symmetry (Oh). The dual of the cuboctahedron is called a deltoidal icositetrahedron. The Bowers acronym for the cuboctahedron is sirco.
