Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be strictly oriented and are deleted.

2NDSNEG₂(s₁(N), cons2₂(X, cons₂(Y, Z))) -> 2NDSPOS₂(N, activate₁(Z))
2NDSPOS₂(s₁(N), cons2₂(X, cons₂(Y, Z))) -> 2NDSNEG₂(N, activate₁(Z))

The remaining pairs can at least by weakly be oriented.

2NDSNEG₂(s₁(N), cons₂(X, Z)) -> 2NDSNEG₂(s₁(N), cons2₂(X, activate₁(Z)))
2NDSPOS₂(s₁(N), cons₂(X, Z)) -> 2NDSPOS₂(s₁(N), cons2₂(X, activate₁(Z)))

Used ordering: Combined order from the following AFS and order.
2NDSNEG₂(x1, x2) = 2NDSNEG₁(x1)
s₁(x1) = s₁(x1)
cons2₂(x1, x2) = cons2
cons₂(x1, x2) = x1
2NDSPOS₂(x1, x2) = 2NDSPOS₁(x1)
activate₁(x1) = x1
n__s₁(x1) = n__s₁(x1)
n__from₁(x1) = n__from₁(x1)
from₁(x1) = from₁(x1)

Lexicographic Path Order [19].
Precedence:

[n_{_from₁}, from_1] > [2NDSNEG₁, s₁, n_{_{s_1]}} > 2NDSPOS₁ > cons2

The following usable rules [14] were oriented:

s₁(X) -> n__s₁(X)
activate₁(n__from₁(X)) -> from₁(activate₁(X))
activate₁(n__s₁(X)) -> s₁(activate₁(X))
activate₁(X) -> X
from₁(X) -> cons₂(X, n__from₁(n__s₁(X)))
from₁(X) -> n__from₁(X)
