Finite state machine of our regulatory network taken as an example in synchronous simulation. The state  colored in green corresponds to a steady state. It has 5 states and itself in its basin of attraction (i.e. the states whose trajectory during the simulation lead to this steady state). The 3 states , ,  colored in red correspond to a state cycle. They have 7 states and themselves in their basin of attraction. All the state space is shown in the figure.
