Abstract

Let G be a finite group and $psi(G)=sum_{gin G}o(g)$, where $o(g)$ denote the order of $g in G$. We show that the Conjecture 4.6.5 posed in [Group Theory and Computation, (2018) 59-90], is incorrect. In fact, we find a pair of finite groups $G$ and $S$ of the same order such that \$psi(G)
