Broken-symmetry solutions of the three-band extended Hubbard model for CuO 2 planes of high-T c superconductors (HTSCs) are investigated. Based on group theoretical arguments, we derive and characterize all types of broken-symmetry phases with a definite symmetry which have an ordering vector q = Q0
