As abstract polytope gad phiddix is isomorphic to sad phiddix, thereby interchanging the roles of ike and gike wrt. real vs. pseudo cells and the likewise changed alignments of tut.

Prarsi is known to be a non-uniform scaliform faceting of gidipthi which uses a (sub-symmetrical) sub-skeleton only. An according full-symmetrical blend of 25 such prarsies (5 per vertex), using modular 2 reductions and blending in turn the co-realmic tricues into ohos, would result in this polychoron.
