Phase synchronization transitions of three coupled Rössler systems. (a) Frequency of each ordinal pattern f(π i), (b) entropy values O and T, (c) mean rotation frequency Ωi of each oscillator. Subsystem k 1 and k 2 are synchronized at κ c1 = 0.036, and k 3 joins the synchronization only at a stronger coupling strength κ c2 = 0.077. Both critical coupling values are highlighted by vertical dashed lines.
