N2 - We determine the patterns of spontaneous symmetry breaking in strong-coupling lattice QCD in a fixed background baryon density. We employ a next-nearest-neighbor fermion formulation that possesses the [Formula Presented] chiral symmetry of the continuum theory. We find that the global symmetry of the ground state varies with [Formula Presented] and with the background baryon density. In all cases the condensate breaks the discrete rotational symmetry of the lattice as well as part of the chiral symmetry group.
