Abstract

Let GG be a finite non-cyclic group. The non-cyclic graph ΓG\Gamma_G of GG is the graph whose vertex set is GCyc(G)G\setminus Cyc(G), two distinct vertices being adjacent if they do not generate a cyclic subgroup, where Cyc(G)={aG:a,b is cyclic for each bG}Cyc(G)=\{a\in G: \langle a,b\rangle\ \text{is cyclic for each } b\in G\}. In this paper, we classify all finite non-cyclic groups GG such that ΓG\Gamma_G has (non)orientable genus one.
