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 oriented strictly and are deleted.

UNQUOTE1(cons1(X, Z)) → UNQUOTE1(Z)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
UNQUOTE1(x1) = x1
cons1(x1, x2) = cons1(x2)

Lexicographic Path Order [19].
Precedence:

trivial

The following usable rules [14] were oriented: none
