Let G be a connected reductive group deΓΏned over an algebraically closed ΓΏeld k of characteristic p ΒΏ 0. The purpose of this paper is two-fold. First, when p is a good prime, we give a new proof of the "order formula" of Testerman for unipotent elements in G; moreover, we show that the same formula
