Looks like a compound of id and a non-uniform faceting of that one, o3β5o, which features again its triangles, but connects those by golden (x,f)-rectangles and then connects these f-edges to f-pentagrams. But in fact the 2 conincident triangles here become Grünbaumian doubly wound hexagons, and the pentagons blend with the inscribed f-pentagrams into complete pentagons. Vertices here coincide by four and x-edges coincide by pairs.
