Looks like a compound of 2 coincident hexacosihecatonicosachora (xhi), and indeed all but the Grünbaumian elements coincide by pairs. It comes in 2 types depending on which cells are Grünbaumian double-covers: type A uses the former truncated tetrahedra (tut) as Grünbaumian double-covered cells, while type B uses the former truncated icosahedra (ti) as such.
