A linear group G ≤ GL(V), where V is a finite vector space, is called 1 2 -transitive if all the G-orbits on the set of nonzero vectors have the same size. We complete the classification of all the 1 ...

Recently S. D. Cohen resolved a conjecture of Chowla and Zassenhaus (1968) in the affirmative by showing that, if f(x) and g(x) are integral polynomials of degree n ≥ 2 and p is a prime exceeding (n2 ...
