A cube 12-compound can be constructed from the vertices of the first dodecahedron 2-compound.
It is implemented in the Wolfram Language as PolyhedronData["CubeTwelveCompound", 1].
The cube 12-compound is illustrated above together with its octahedron 12-compound dual and common midsphere.
The common solid and convex hull are unnamed polyhedra illustrated above.
