Acronym ..., rigfix || quipdohi Name (degenerate) rigfix atop quipdohi Circumradius ∞   i.e. flat in euclidean space Confer general polytopal classes: decomposition

It either can be thought of as a degenerate 5D segmentotope with zero height, or as a 4D euclidean decomposition of the larger base into smaller bits.

As abstract polytope rigfix || quipdohi is isomorphic to padohi || rofix, thereby interchanging the roles of pentagrams and pentagons, resp. replacing pip by stip, gike by ike, and interchanging the roles of sissid and gad, of peppy and stappy, resp. replacing rigfix by rofix, pippy by stippy, gikagid by ikaid, and quipdohi by padohi.
