This complex polychoron is somewhat special in so far as its edges, faces, and calls all are degenerate, i.e. remain real space polytopes only. However, its vertex figure is the truely complex polyhedron x2-3-o2-4-o4. Thence it still remains embeddable into a real space polyzetton, in fact into the tegum product of 4 (fully orthogonal) squares. In fact the to be chosen cells are just the lacing tets, which have one vertex on each of those squares.
