Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

2NDSNEG2(s1(N), cons22(X, cons2(Y, Z))) -> 2NDSPOS2(N, activate1(Z))
2NDSPOS2(s1(N), cons22(X, cons2(Y, Z))) -> 2NDSNEG2(N, activate1(Z))
Used argument filtering: 2NDSNEG2(x1, x2)  =  x1
s1(x1)  =  s1(x1)
2NDSPOS2(x1, x2)  =  x1
n__s1(x1)  =  n__s
Used ordering: Quasi Precedence: s_1 > n__s
