We have to consider all minimal (P,Q,R)-chains.
We have reversed the following QTRS:
The set of rules R is

b(a(a(x))) → a(a(a(c(b(b(x))))))
a(c(b(x))) → x
b(a(A(x))) → A(x)
b(a(b(a(A(x))))) → a(a(a(c(b(b(a(A(x))))))))
b(a(A(x))) → a(A(x))
b(b(a(A(x)))) → a(a(a(c(b(b(A(x)))))))

The set Q is empty.
We have obtained the following QTRS:

a(a(b(x))) → b(b(c(a(a(a(x))))))
b(c(a(x))) → x
A(a(b(x))) → A(x)
A(a(b(a(b(x))))) → A(a(b(b(c(a(a(a(x))))))))
A(a(b(x))) → A(a(x))
A(a(b(b(x)))) → A(b(b(c(a(a(a(x)))))))

The set Q is empty.
