3.20/1.76	ConCon could not decide confluence of the system.
3.20/1.76	\cite{ALS94}, Theorem 4.1 does not apply.
3.20/1.76	This system is of type 3 or smaller.
3.20/1.76	This system is strongly deterministic.
3.20/1.76	This system is quasi-decreasing.
3.20/1.76	By \cite{A14}, Theorem 11.5.9.
3.20/1.76	This system is of type 3 or smaller.
3.20/1.76	This system is deterministic.
3.20/1.76	System R transformed to V(R) + Emb.
3.20/1.76	This system is terminating.
