A point in the Mandelbrot Set that is at the end of a filament (as opposed to a branch point); a point from which there is only one path to other points in the Mandelbrot Set.
Some of these have limit cycles with a period, an example is 0+i. However, these are repelling periodic points: All nearby points have different periods or escape entirely.
See External Angle.
