Query: Regular orbits of finite primitive solvable groups, the final
  classification   Suppose that a finite solvable group $G$ acts faithfully, irreducibly and
quasi-primitively on a finite vector space $V$, and $G$ is not metacyclic. Then
$G$ always has a regular orbit on $V$ except for a few "small" cases. We
completely classify these cases in this paper.
