Looks like a compound of 2 coincident small rhombated tesseract (srit). And indeed all but the Grünbaumian elements coincide by pairs. It occurs in different types. Type A uses pairs of coincident small rhombicuboctahedra (sirco), while all other cells are doubly covered. Type B uses pairs of coincident triangular prisms (trip), while all other cells are doubly covered.
