You probably wan to restrict to irreducible groups in 1) and 2) (in 1) that's intended to mean ireducible as a rational linear group). Question 2) is equivalent to determining the finite subgroups of ${\rm GL}(n,\mathbb{Q})$ up to equivalence. For example, Feit determned the finite irreducible subgroups of ${\rm GL}(11,\mathbb{Q})$ prior to the classification of finite simple groups. Question 2) is more amenable to attack, at least for irreducible groups. In the irreducible case, the prime factorization of $n$ is relevant, as well as the size. It's easier for prime $n$ | |
