Long-range (r ~ p ~-~ >> lattice spacing) spin-wave exchange produces a very strong pairing of the holes. Solutions of the BCStype equation for the superconducting gap A are found for various symmetries. The strongest pairing corresponds to d wave symmetry. The physical reasons for the strong pairin
