Algebra seminar - Patricia Medina-Capilla
14:00 - 15:00 11 March 2025
Title: The second maximal subgroups of the almost simple groups Abstract: In 2018, Lucchini, Marion, and Tracey showed that every maximal subgroup of an almost simple group is 5-generated, lowering the previously known bound of 6. Naturally, one can ask the same about second maximal subgroups of almost...
