uniform relative:
gike   gid  
related Johnson solids:

general polytopal classes:
expanded kaleido-facetings  

Similar to thawro, likewise githawro can be obtained by means of an expanded kaleido-faceting, but here by starting with gike instead.

As abstract polytope githawro is isomorphic to thawro, thereby replacing pentagrams by pentagons.
