Type Uniform compound
Index UC12
Convex hull Nonuniform truncated cube

Vertices 24
Symmetry group octahedral (Oh)

This uniform polyhedron compound is a symmetric arrangement of 4 octahedra, considered as triangular antiprisms. It can be constructed by superimposing four identical octahedra, and then rotating each by 60 degrees about a separate axis (that passes through the centres of two opposite octahedral faces).

Cartesian coordinates[edit]

Cartesian coordinates for the vertices of this compound are all the permutations of

(±2, ±1, ±2)
