If f f has a periodic point of least period n n, then f f has a periodic point of least period k k, for each k k such that n≻ k n ≻ k .

One of the implications of the theorem is that if a discrete dynamical system on the real line has a periodic point of period 3, then it must have periodic points of every other period.
