A classification of the equilibrium states of single-sublattice magnets with spin s = 3/2 and SU(4) symmetry of the exchange interaction is developed. The study is based on the concept of quasi-averages and the principle of residual symmetry of degenerate equilibrium states. The transformation properties of the magnetic degrees of freedom are used to derive a system of equations for the order parameters and to find their solutions. The equilibrium structure of these degrees of freedom is presented in terms of the parameters of the residual symmetry generator.
