Abstract

In this talk, I will present recent results concerning pairwise generating sets in alternating and symmetric groups, joint works with A. Maro ́ti (R ́enyi Institute of Mathematics, Budapest, Hungary), F. Fumagalli and P. Gheri (University of Firenze, Italy). Given a finite 2-generated group G, a subset S of G is said to be a pairwise generating set if any two distinct elements of S generate G. We study the maximal size of a pairwise generating set of G, denoted ω(G), in case G is an alternating or symmetric group. This is the clique number (i.e. the maximal size of a complete subgraph) of the so-called generating graph of G, whose vertices are the elements of G and two vertices are connected by an edge if they generate G.
