AB - Let $G$ be a permutation group on a set $\Omega$ with no fixedpoints in $\Omega$ and let $m$ be a positive integer. If noelement of $G$ moves any subset of $\Omega$ by more than $m$points (that is, if $|\Gamma^g \setminus \Gamma|\leq m$ for every$\Gamma \subseteq \Omega$ and $g\in G$), and the lengths of allorbits are not equal to $2$. Then the number $t$ of $G$-orbits in $\Omega$ is at most $2m-2$. Moreover, the groups attaining the maximum bound $t=2m-2$ will be classified. \vspace{.4cm}\\
