"Let G be a finite, primitive subgroup of GL(V) = GL(n,D), where V is an n-dimensional vector space over the division ring D. Assume that G is generated by 'nice' transformations. The problem is then to try to determine (up to GL(V)-conjugacy) all possibilities for G. Of course, this problem is very vague. But it is a classical one, going back 150 years, and yet very much alive today."
