Summary: We continue our analysis of relativistically invariant systems [cf. ibid. 111, No. 2, 242-251 (1997)] and perform the reduction of the number of field states. Expression for the integrals of motion are given in the zeroth order in the inverse powers of the coupling constant in the form of derivatives with respect to group variables.
