Abstract: Possible generalizations of the Ashkin-Teller model are analysed aiming at reduction of degeneracy of the energy levels. The extended isotropic case is considered in the framework of the molecular field approximation. Assuming six order parameters a three dimensional phase diagram is calculated.
