As abstract polytope sidtixhi is isomorphic to gidtixhi, thereby replacing gike by ike.

From the unit circumradius it follows, when considered with according densities, that then sidtixhi can be thought of as the external blend of 600 pens + 120 gikepies. This decomposition is described as the degenerate segmentoteron ox3oo3oo3oo5/2*b&#x.
