As abstract polytope xhi is isomorphic to gixhi, thereby replacing the pentagons by pentagrams, resp. replacing ti by tiggy.
Note that xhi can be thought of as the external blend of 1 srahi + 600 octatuts + 1200 triddips + 120 sridaties. This decomposition is described as the degenerate segmentoteron oo3xx3ox5xo&#x.
