3.26/1.61	Obligation:
3.26/1.61	Q restricted rewrite system:
3.26/1.61	The TRS R consists of the following rules:
3.26/1.61	
3.26/1.61	   a(a(a(x1))) -> b(a(b(x1)))
3.26/1.61	   b(a(b(x1))) -> a(b(a(x1)))
3.26/1.61	
3.26/1.61	Q is empty.

3.26/1.61	(1) NonTerminationProof (COMPLETE)
3.26/1.61	We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
