## Detecting preperiodic points

In brief, I require to confirm whether I have preperiodic orbits or straying orbits for some dynamical systems. Not as brief: Let $\phi$ be a sensible map. Intend we need to know if 0 is preperiodic under $\phi$. Certainly if it were, were can iterate constantly till locating some $i,j$ with $i\neq j$ and also $\phi^i(0) = \phi^j(0)$, nonethele...
