Looks like a compound of 2 octahedra (oct) plus the 3 pairs of diametral squares each, and indeed edges and {4} coincide by four, but vertices and {3} coincide by pairs. Just as oct+6{4} also can be seen as joined pair of mutually inverted thah, this one can be seen as joined pair of mutually inverted 2thah.
