Abstract
Let G be a finite group with exactly k elements of largest possible order m. Let q(m) be the product of gcd (m, 4) and the odd prime divisors of m. We show that | G| ≤ q(m) k 2/ φ(m) where φ denotes Euler’s totient function. This strengthens a recent result of Cocke and Venkataraman. As an application we classify all finite groups with k< 36. This is motivated by a conjecture of Thompson and unifies several partial results in the literature.
