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

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

Q is empty.

(1) NonTerminationProof (COMPLETE transformation)

We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
