Acronym ...
Name complex polyhedron xp   xr-4-o2,
complex polyhedron xp   xr   xr
Face vector pr2, 2(p+r)r, p+2r
Especially xp   xp   xp (p=r=t)  
Confer
more general:
xp   xr   xt  
real space embedding:
(p,r,r)-triprism
general polytopal classes:
complex polytopes  

This reducible complex polyhedron similarily can be embedded into the triprism (p,r,r)-tip (provided that p,r>2), then again selecting its vertices, its various base polygons (for according complex edges), and the subset of either those polygon pairings from the according duoprisms (for the respective complex faces).
