116.82/30.75	Proof:
116.82/30.75	ConCon could not decide confluence of the system.
116.82/30.75	\cite{ALS94}, Theorem 4.1 does not apply.
116.82/30.75	This system is of type 3 or smaller.
116.82/30.75	This system is strongly deterministic.
116.82/30.75	This system is of type 3 or smaller.
116.82/30.75	This system is deterministic.
116.82/30.75	ConCon could not decide if this system is quasi-decreasing.
116.82/30.75	\cite{O02}, p. 214, Proposition 7.2.50 does not apply.
116.82/30.75	This system is of type 3 or smaller.
116.82/30.75	This system is deterministic.
116.82/30.75	System R transformed to optimized U(R).
116.82/30.75	The external tool could not decide termination of the system.
