Abstract: Let \(V\) be a finite vector space over a field of prime order. Recall that a remarkable result of Hering in 1985 classifies the subgroups of \(\mathrm{GL}(V)\) which act transitively on non-zero vectors. Later in 1987, Liebeck gave a complete classification of irreducible subgroups of \(\mathrm{GL}(V)\) with exactly \(3\) orbits on \(V\). In this talk, we analyze reducible subgroups of \(\mathrm{GL}(V)\) with exactly \(3\) orbits, which is a step towards a classification of finite permutation groups of rank \(3\). Joint work with Cai Heng Li and Yan Zhou Zhu.
