Similar to thawro, likewise githawro can be obtained by means of an expanded kaleido-faceting, but here by starting with gike instead.
This polyhedron further is related not only to gid (that central 3 pentagrams plus 4 triangles patch) but also to qrid (the 3 lunes out of a square and 2 attached triangles each).
As abstract polytope githawro is isomorphic to thawro, thereby replacing pentagrams by pentagons.
