doc=The interior fixed point <math>\hat x</math> is an unstable focus. Near <math>\hat x</math> all trajectories spiral away but the boundary of the simplex <math>S_3</math> is repelling because of mutations, which gives rise to a stable limit cycle. For larger mutation rates the interior fixed point becomes stable again even for <math>s<1</math>.
