The (complex) faces are x5-4-o2, the (complex) cells are x5-4-o2-3-o2, and the vertex figure here is just x2-3-o2-3-o2, i.e. nothing but the real space tet.

The below various incidence representations are direct, next dimensional consequences from what was explained already at xp-4-o2 = xp   xp. I.e. the according cartesian or prism product applies for complex polytopes alike. In fact, these complex polychora simply re-use the even-dimensional elements of all the pentagons, pedips, and pettips from this real quadprism only.
