square₁(X) -> times₂(X, X)

The set Q consists of the following terms:

from₁(x0)
2ndspos₂(0, x0)
2ndspos₂(s₁(x0), cons₂(x1, x2))
2ndspos₂(s₁(x0), cons2₂(x1, cons₂(x2, x3)))
2ndsneg₂(0, x0)
2ndsneg₂(s₁(x0), cons₂(x1, x2))
2ndsneg₂(s₁(x0), cons2₂(x1, cons₂(x2, x3)))
pi₁(x0)
plus₂(0, x0)
plus₂(s₁(x0), x1)
times₂(0, x0)
times₂(s₁(x0), x1)
square₁(x0)

We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
