The orbits of B and C tend to the 2-cycle 0 --> -1 --> 0 --> -1 --> .... That is. each of these orbits has some "transient behavior" before getting closer and closer to the 2-cycle.
The orbits of E and H apparently wander around the boundary of the filled Julia set without tending to infinity or to the 2-cycle. With the limited number of points shown, it is not possible to determine if these orbits eventually cycle or simply keep moving around the boundary without ever returning to a previous point on the orbit.
The orbits of F and G are fixed points. x2 - 1
