 Misiurewicz point

In mathematics, a Misiurewicz point is a parameter in the Mandelbrot set (the parameter space of quadratic polynomials) for which the critical point is strictly preperiodic (i.e., it becomes periodic after finitely many iterations but is not periodic itself).By analogy, the term "Misiurewicz point" is also used for parameters in a Multibrot set where the unique critical point is strictly preperiodic.
