Helmut Wielandt discussed an old question(Chap. 2, Section 15, which can be dated back to Camille Jordan):

Let $g\neq 1$ be a permutation in some finite primitive permutation group $G$ of degree $n$. The minimal degree $m$ is defined to be the least number of points that $g$ permutes. It is known that if $m>3$, then $n$ is bounded by $$\frac{m^2}{4}\log\frac{m}{2}+m\left(\log\frac{m}{2}+\frac{3}{2}\right).$$

Question: Do we know a better upper bound today(with CFSG and O'Nan-Scott etc.)?
