Termination w.r.t. Q of the following Term Rewriting System could not be shown:

Q restricted rewrite system:
The TRS R consists of the following rules:

p₁(s₁(x)) -> x
fac₁(0) -> s₁(0)
fac₁(s₁(x)) -> times₂(s₁(x), fac₁(p₁(s₁(x))))

Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:

p₁(s₁(x)) -> x
fac₁(0) -> s₁(0)
fac₁(s₁(x)) -> times₂(s₁(x), fac₁(p₁(s₁(x))))

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.
