For nanodots in a saturated state, the effect of perturbations of all possible symmetries on the three-magnon processes is systematized, and the relation between perturbation symmetry and symmetry of the modes involved in a three-magnon process affected by the perturbation is esteblished. It was found that mode hybridization in multilayer nanostructures can be an efficient mechanism for controlling four-magnon processes and, accordingly, the second-order parametric instability.
