Large maximal subgroups of almost simple classical groups (2506.23048v1)
Published 29 Jun 2025 in math.GR
Abstract: A proper subgroup $H$ in a finite group $G$ is said to be large if $|H|3\geq |G|$. In this paper, we determined all large maximal subgroups of almost simple classical groups. Combined with the work of Alavi and Burness (J. Algebra 421 (2015) 187--233) and Alavi, Bayat, and Daneshkhah (J. Algebraic Combin. 55 (2022) 729--779), this completes the classification of all large maximal subgroups of almost simple groups.
