Mathematics, 2020 The structure of the commutator subgroup of Sylow 2-subgroups of an alternating group A 2 k is determined. This work continues the previous investigations of me, where minimal generating sets for Sylow 2-subgroups of alternating groups were ...

Characterising Locally Finite Groups Satisfying the Strong Sylow Theorem for the Prime p [PDF]
Advances in Group Theory and Applications, 2022 During his lectures to the 1987 Singapore Group Theory Conference Otto H. Kegel proposed the following question: “If every subgroup S of the locally finite group G contains a finite p-subgroup which is singular in S, does G then satisfy the strong Sylow ...

Finite groups with seminormal or abnormal Sylow subgroups [PDF]
International Journal of Group Theory, 2020 Let $G$ be a finite group in which every Sylow subgroup is seminormal or abnormal. We prove that $G$ has a Sylow tower. We establish that if a group has a maximal subgroup with Sylow subgroups under the same conditions, then this group is ...

Influence of the number of Sylow subgroups on solvability of finite groups
Comptes Rendus. Mathématique, 2021 Let $G$ be a finite group. We prove that if the number of Sylow $3$-subgroups of $G$ is at most $7$ and the number of Sylow $5$-subgroups of $G$ is at most $1455$, then $G$ is solvable. This is a strong form of a recent conjecture of Robati.

On z-Reachable Subgroups of Finite Groups [PDF]
Advances in Group Theory and Applications, 2023 A finite group G is a z-group if every Sylow subgroup of G is cyclic. A subgroup H of a group G is called c-reachable (z-reachable) in G if there is a subgroup chain H = H0 ≤ H1 ≤ ... ≤ Hi ≤ Hi+1 ≤ ... ≤ Hn−1 ≤ Hn = G such that Hi+1 = HiKi, where Ki is a

Sylow Subgroups in Parallel [PDF]
Journal of Algorithms, 1999 This paper presents efficient (NC) parallel algorithms for finding and conjugating Sylow subgroups of permutation groups. Like the sequential polynomial-time algorithms developed by Kantor over a dozen years earlier, these algorithms involve reducing to the case of simple groups and then using the classification of finite simple groups to provide a ...

Groups Factorized by Pairwise Permutable Abelian Subgroups of Finite Rank [PDF]
Advances in Group Theory and Applications, 2016 It is proved that a group which is the product of pairwise permutable abelian subgroups of finite Prüfer rank is hyperabelian with finite Prüfer rank; in the periodic case the Sylow subgroups of such a product are described.

Influence of complemented subgroups on the structure of finite groups [PDF]
International Journal of Group Theory, 2021 P. Hall proved that a finite group $G$ is supersoluble with elementary abelian Sylow subgroups if and only if every subgroup of $G$ is complemented in $G$. He called such groups complemented. A. Ballester-Bolinches and X.

Centers of Sylow subgroups and automorphisms [PDF]
Israel Journal of Mathematics, 2020 Suppose that p is an odd prime and G is a finite group having no normal non-trivial p'-subgroup. We show that if a is an automorphism of G of p-power order centralizing a Sylow p-group of G, then a is inner. This answers a conjecture of Gross. An easy corollary is that if p is an odd prime and P is a Sylow p-subgroup of G, then the center of P is ...
