This polychoron either can be derived as a diminishing of the EKF ((oFFxx3xxoof3fooxo3ooffx))&#zx (removing the 3rd layer). Alternatively these processes could be commutated here: starting from ex in pentic subsymmetry, which can be given as ((xffoo3oxoof3fooxo3ooffx))&#zx, one first deletes the 3rd layer, the vertex set of a vertex inscribed f-scaled spid, resulting in ((xf.oo3ox.of3fo.xo3oo.fx))&#zx. Thereon one then applies the kaleido faceting wrt. the first node in the first layer, resulting in (((-x)f.oo3xx.of3fo.xo3oo.fx))&#zx. Finally one applies the Stott expansion wrt. the first node, which reproduces this polychoron alike.

Incidence matrix according to Dynkin symbol

((oFxx3xxof3foxo3oofx))&#zx   → all heights = 0 – except those of the not existing lacing(1,2) resp. lacing(2,3).
