Description	Journal: Journal of Physics C: Solid State Physics A system of localised spins s=1 with the bilinear Heisenberg $S_{f}.S_{f'}$, biquadratic (S_{f}.S_{f'}$)^{2}$ and three-atom $(S_{f}.S_{g})(S_{g}.S_{f'}$) interactions is considered. Using Anderson's method (1951) sufficient conditions are established for the ferromagnetic state to be the exact ground state.
