117.56/30.83	Proof:
117.56/30.83	ConCon could not decide confluence of the system.
117.56/30.83	\cite{ALS94}, Theorem 4.1 does not apply.
117.56/30.83	This system is of type 3 or smaller.
117.56/30.83	This system is strongly deterministic.
117.56/30.83	This system is of type 3 or smaller.
117.56/30.83	This system is deterministic.
117.56/30.83	ConCon could not decide if this system is quasi-decreasing.
117.56/30.83	\cite{O02}, p. 214, Proposition 7.2.50 does not apply.
117.56/30.83	This system is of type 3 or smaller.
117.56/30.83	This system is deterministic.
117.56/30.84	System R transformed to optimized U(R).
117.56/30.84	The external tool could not decide termination of the system.
