Abstract

The main goal of the paper is to compute the number of group actions and actions up to isomorphism of a finitely generated Abelian group $ G \cong \mathbb{Z}^k \oplus \mathbb{Z}_{d_1} \oplus \cdots \oplus \mathbb{Z}_{d_t} $, on a set of \(m\) elements, and several illustrative examples are presented to clarify the main results.
