Suggestion for fractal textbook

[htadashi]

In the Mandelbrot set section of fractal textbook it is written that

In some cases, the sequence doesn’t converge to a single point – instead it reaches a cycle of multiple points, like a triangle. These cycles are called orbits.

Many textbooks on dynamical systems call these cycles as periodic orbits, and the term orbit is used to refer to any trajectory of the dynamical system. Should not be better to change 'orbits' to 'periodic orbits'?
