Let G be a finite group and let Irr(G) be the set of irreducible characters of G . We say that an element g in G is a vanishing element if there exists some χ∈ Irr(G) such that χ(g)=0 . In this paper, we provide a relatively short proof for the classification of finite groups whose set of vanishing elements is the :union: of exactly three conjugacy classes.
