 		The learned model also contains states, therefore they must be equivalent.

+		A counter-example $\pi$ consists of a prefix, an input where an inconsistency appears and a suffix showing the inconsistency:
+			$\pi = \sigma u \rho$.
+		However, when we provide some sequence $\pi$ it may be possible to find distinct partitions
+			$\pi = \sigma_1 u_1 \rho_1 \neq \sigma_2 u_2 \rho_2 = \pi$
+			which both help to improve the hypothesis.
+		If on the first run we add $\rho_1$ to the suffices of our table,
+			$\sigma_2 u_2 \rho_2$ may not be covered yet,
+			and we may be able to add $\pi$ a second time.
