The disnub cuboctahedron, disco, or compound of two snub cubes is a uniform polyhedron compound. It consists of 48 snub triangles, 16 further triangles, and 12 squares (the latter two can combine in pairs due to faces in the same plane). Four triangles and one square join at each vertex.

Its quotient prismatic equivalent is the snub cubic antiprism, which is four-dimensional.

Measures[edit | edit source]

The circumradius R ≈ 1.34371 of the disnub cuboctahedron with unit edge length is the largest real root of

Its volume V ≈ 15.77896 is given by the largest real root of


Its dihedral angles can be given as acos(α) for the angle between two triangular faces, and acos(β) for the angle between a square face and a triangular face, where α ≈ –0.89286 equals the unique real root of

and β ≈ –0.79846 equals the unique negative real root of


Vertex coordinates[edit | edit source]

A disnub cuboctahedron of edge length 1 has coordinates given by all permutations of:

  • c1, ±c2, ±c3),
