As will be seen from fig. 46 and 47 the pyritohedron exists in complementary forms, fig. 46 being known as the plus and fig. 47 as the minus form. The 24 faces of the plus and minus pyiitohedrons have the same position in space as the 24 faces of the corresponding tetrahexahedron of the normal group. Diploid.
