In previous work [4], the author claimed a characterization for F_G(n) and lower asymptotic bounds for Conj_G(n) when G is a finitely generated nilpotent group. However, a counterexample to the characterization of F_G(n) for finitely generated nilpotent groups was communicated to us by Khalid Bou-Rabee which also had consequences to the lower asymptotic bound provided for Conj_G(n). The purpose of this note to explain what is incorrect in [4] along with the counterexample provided to us. We will also explain what remains correct in [4] and how we obtain weaker lower bounds for F_N(n) and Conj_N(n) which are found in the author's thesis and a forthcoming preprint.
