A cuboctahedron is a uniform three-dimensional polyhedron that can be constructed by rectifying a cube. It can also be created by rectifying an octahedron, or by cantellating a tetrahedron (when considered with this symmetry, it can be called a rhombitetratetrahedron).

As a rectified octahedron, it has the same symmetry group as the octahedron, namely octahedral symmetry (Oh).

The dual of the cuboctahedron is called a rhombic dodecahedron.

The Bowers acronym for the cuboctahedron is co.

## Symbols

Dynkin based symbols of the cuboctahedron include:

• o4x3o (full symmetry)
• x3o3x (rhombitetratetrahedron)
• xox4oqo&#xt (square symmetry)
• xxo3oxx&#xt (triangular gyrobicupola)
• oxuxo oqoqo&#xt (vertex first)
• qo xo4oq&#zx (square prism symmetry)
• qqo qoq oqq&#zx (block symmetry)

## Structure and Sections

On each vertex of the cuboctahedron, two triangles and two squares join.

### Hypervolumes

• vertex count = • edge length = • surface area = • surcell volume = ### Subfacets

• Vertex radius: • Edge radius: • Triangle radius: • Square radius: ### Angles

• Dihedral angle: ### Vertex coordinates

The vertex coordinates of a cuboctahedron with length 2 are all permuations of (±√2,±√2,0).
