The blended octahedron, or skew octahedron, is a regular skew polyhedron in 4D Euclidean space. It is the result of blending an octahedron with a dyad.

The blended octahedron and its Petrie dual, the blended Petrial octahedron are realizations of the same abstract regular polytope, however they are not equivalent.

This underlying abstract polytope has faithful symmetric realizations, including the blended octahedron and its Petrial, however it has no pure faithful symmetric realizations. That is, it cannot be expressed without a blend or coincident vertices.
