Abstract
We show that, for every transitive permutation group (Formula presented.) of degree (Formula presented.), the largest abelian quotient of (Formula presented.) has cardinality at most (Formula presented.). This gives a positive answer to a 1989 outstanding question of László Kovács and Cheryl Praeger.
