On the strong connectivity of the 2-Engel graphs of almost simple groups

Group Theory 2023-04-20 v1 Combinatorics

Abstract

The Engel graph of a finite group GG is a directed graph encoding the pairs of elements in GG satisfying some Engel word. Recent work of Lucchini and the third author shows that, except for a few well-understood cases, the Engel graphs of almost simple groups are strongly connected. In this paper, we give a refinement to this analysis.
