The Derived Subgroups of Sylow 2-Subgroups of the Alternating Group, Commutator Width of Wreath Product of Groups

open access: yesMathematics, 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]

open access: yesAdvances 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]

open access: yesInternational 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

open access: yesComptes 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]

open access: yesAdvances 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

Groups Factorized by Pairwise Permutable Abelian Subgroups of Finite Rank [PDF]

open access: yesAdvances 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.

Sylow multiplicities in finite groups [PDF]

open access: yesInternational Journal of Group Theory, 2018
Let $G$ be a finite group and let $mathcal{P}=P_{1},ldots,P_{m}$ be a sequence‎ ‎of Sylow $p_{i}$-subgroups of $G$‎, ‎where $p_{1},ldots,p_{m}$ are the distinct‎ ‎prime divisors of $leftvert Grightvert $‎. ‎The Sylow multiplicity of $gin‎ ‎G$ in $mathcal{

Influence of complemented subgroups on the structure of finite groups [PDF]

open access: yesInternational 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.

On the solvability of finite groups and the number of Sylow 2-subgroups [PDF]

open access: yesEuropean Journal of Mathematics and Applications, 2022
Let $G$ be a finite group. Denoted by $n_2(G)$ the number of Sylow $2$-subgroups of $G$. In this paper, we prove if $G$ is non-solvable and $n_2(G)$ is a power of a prime $p$, then $p$ is a Fermat prime.

A Simple Classification of Finite Groups of Order p2q2 [PDF]

open access: yesMathematics Interdisciplinary Research, 2018
‎Suppose G is a group of order p2q2 where p>q are prime numbers and suppose P and Q are Sylow p-subgroups and Sylow q-subgroups of G, ‎respectively‎. ‎In this paper‎, ‎we show that up to isomorphism‎, ‎there are four groups of order p2q2 when Q and P are
