non-Grünbaumian master:
prix  

Looks like a compound of 2 prismatorhombated hexacosichora (prix), and indeed all but the Grünbaumian elements coincide by pairs. It comes in different types depending on which cells are Grünbaumian: type A uses all but the decagonal prisms (dip) as Grünbaumian cells, while in type B additionally the triangular prisms (trip) come in coincident pairs.
