This complex polyhedron is somewhat special in so far as both its edges as well as its faces remain mere real polytopes. The vertex figure however, becomes the complex polygon x₂-4-o₄. Thence it not only is the formal dual of the complex polytope x₄-4-o₂-3-o₂, but also its real space embedding is still 6-dimensional and is the dual of that there given one, i.e. the tegum poduct of 3 (fully orthogonal) squares. In fact, the to be chosen triangles therefrom are just those lacing triangles, which have one vertex on each of those squares. For the provided metrical properties the overall scaling of that embedding is to be chosen such that those lacing edges become unity.

The incidence matrix thence is simply the same as for Shephard's 4-generalised cube, just rotated 180° around
