A finite set of points towards which the iterates Zn converge in an asymptotic manner during iteration. A limit cycle is also called an attractor.
When iteration diverges or is chaotic (failing to diverge or converge) there is no attractor and "limit cycle" is undefined for that iteration.
The number of points in a limit cycle is called the period.
