Saying a point $p$ is fixed by $f^m$ means that applying the function $f$ exactly $m$ times to $p$ returns $p$ itself. This rephrases the definition of a periodic point of period $m$ as a fixed point of the $m$-fold iterate of $f$.

Conditions: $f$ is a function.; $m$ is a positive integer.; $p$ is a point in the domain of $f$.
