Abstract: In this paper, the method to determine all parameters a for MCS(x_nΞax_n-1(modM),n ≥ 1) with any Period m is given on the basis of the theorems in1 We deduce the parameters a from seeking m orders unit root for modul M' (M'=M/d, (x₀,M)=d)and propose the simplified algorithms to do so for the composite m. A numerical example shows the correctness of the method.
