Analysis of coexistence of two sequences of length according to method M3.

Second column shows the number of scanned sequences (the whole combined sequence space for all investigated ). The third column shows the fraction of coexisting sequences, i.e. the probability of coexistence of two sequences with a given parameter set (see Text S1). (S) indicates that all cases of coexistence are locally asymptotically stable. The fourth column shows the average of the leading eigenvalues (if coexistence exists) as a measure of stability.
