Looks like a compound of gahi and gohi with vertices and edges identified, while faces coincide by pairs.

As abstract polytope gahi+gohi is isomorphic to gishi+gashi, thereby just scaling the edge figure, a complete pentagon, resp. replacing doe by gissid, gad by sissid, and replacing gacid vertex figures by cid ones.

Just as gacid itself (with vertices being identified) comes in 2 flavors, type A) as in o5/3x3o5*a with vertex figure [(5/3,3)5] or type B) as in o5/3o5/2x3*a with vertex figure [(5/2,3)5]/3, accordingly either one can be used as vertex figure here too. Thus gahi+gohi comes alike in 2 corresponding flavors (types being marked accordingly).
