calculus

Let S be a finite subset of rational number (Q) S ={x1,x2,x3.......xn} and f(x)=x-1∖x. Define R1 = {f(x1),f(x2),f(x3).......f(x4)} and S1= R1∩S R2 = {f(f(x1) ,f(f(x2 ) , f(f(x3 ) , .......f(f(xn ) and S2 =R2∩S and so on (S do not contain -1,0,1), prove that there exists (n∈N) such that Sn = Sn+1 = Sn+2 = ........∞=φ
