title = "Non-vanishing elements of finite groups",

abstract = "Let G be a finite group, and let Irr (G) denote the set of irreducible complex characters of G. An element x of G is non-vanishing if, for every χ in Irr (G), we have χ (x) ≠ 0. We prove that, if x is a non-vanishing element of G and the order of x is coprime to 6, then x lies in the Fitting subgroup of G.",
