The critical properties of the mixed ferro/antiferromagnetic q -state Potts model on the square lattice are investigated using the numerical transfer matrix technique. The transition temperature is found to be substantially lower than previously found for q = 3. It is conjectured that there is no transition for q > 3, in contradiction with previous results.
