So we could mention these operations, which take the cube to the 237:(1954) in their famous paper on uniform polyhedra do indeed refer to what we could call quasicantellation and quasicantitruncation, although of course not under those names: they call them instead r'{ 337:
Is there a common terminology for the opposite of a truncation, namely the "drawing out" of faces until they become vertices? The images on the right show, that "untruncating" the dark faces of a
