Abstract:
In this short note, we give a new Menon-type identity involving the sum of element or-ders and the sum of cyclic subgroup orders of a finite group. It is based on applying the weighted form of Burnside’s lemma to a natural group action.
Keywords:
Menon’s identity, weighted Burnside’s lemma, group action, sum of element orders, sum of cyclic subgroup orders.
