The truncated cuboctahedron is an Archimedean solid. It has 12 regular square faces, 8 regular hexagonal faces, 6 regular octagonal faces, 48 vertices and 72 edges. Since each of its faces has point symmetry (equivalently, 180° rotational symmetry), the truncated cuboctahedron is a zonohedron.

Other names

Alternate interchangeable names are:

  • Rhombitruncated cuboctahedron
  • Great rhombicuboctahedron
  • Omnitruncated cuboctahedron

The name truncated cuboctahedron, given originally by Johannes Kepler, is a little misleading. If you truncate a cuboctahedron by cutting the corners off, you do not get this uniform figure: some of the faces will be rectangles. However, the resulting figure is topologically equivalent to a truncated cuboctahedron and can always be deformed until the faces are regular. Johannes Kepler (December 27, 1571 – November 15, 1630) was a German Lutheran mathematician, astronomer and astrologer, and a key figure in the 17th century astronomical revolution. ... A truncated cube - faces double in sides, and vertices replaced by new faces. ... In geometry, a rectangle is defined as a quadrilateral where all four of its angles are right angles. ... A Möbius strip, a surface with only one side and one edge; such shapes are an object of study in topology. ...


The alternative name great rhombicuboctahedron refers to the fact that the 12 square faces lie in the same planes as the 12 faces of the rhombic dodecahedron which is dual to the cuboctahedron. Compare to small rhombicuboctahedron. The rhombic dodecahedron is a convex polyhedron with 12 rhombic faces. ... A cuboctahedron is a polyhedron with eight triangular faces and six square faces. ... The rhombicuboctahedron, or small rhombicuboctahedron, is an Archimedean solid with eight triangular and eighteen square faces. ...


One unfortunate point of confusion: There is a nonconvex uniform polyhedron by the same name. See uniform great rhombicuboctahedron. In geometry, the Uniform great rhombicuboctahedron is a nonconvex uniform polyhedron, indexed as U17. ...


Cartesian coordinates

Cartesian coordinates for the vertices of a truncated cuboctahedron centered at the origin are all permutations of Cartesian means relating to the French mathematician and philosopher Descartes, who, among other things, worked to merge algebra and Euclidean geometry. ...

Since each of its faces has point symmetry (equivalently, 180° rotational symmetry), the truncated cuboctahedron is a zonohedron.
If you truncate a cuboctahedron by cutting the corners off, you do not get an actual regular truncated cuboctahedron: some of the faces will be irregular polygons.
The alternative name great rhombicuboctahedron refers to the fact that the 12 square faces lie in the same planes as the 12 faces of the rhombic dodecahedron which is dual to the cuboctahedron.
