Steiner triple systems with doubly transitive automorphism groups: A corollary to the classification theorem for finite simple groups

open access: closedJournal of Combinatorial Theory, Series A, 1984
The authors supply a proof, based on the Classification Theorem for finite simple groups, that a Steiner triple system whose automorphism is doubly transitive on points is a projective geometry over GF(2) or an affine geometry over GF(3). This was a conjecture of \textit{M. Hall jun.} [Proc. Symp. Pure Math. 6, 47-66 (1962; Zbl 0114.012)].

On Flag-Transitive, Point-Quasiprimitive Symmetric 2-(v,k,λ) Designs with λ Prime

open access: yesMathematics, 2023
This paper contributes to the classification of flag-transitive symmetric 2-(v,k,λ) designs with λ prime. We investigate the structure of flag-transitive, point-quasiprimitive automorphism groups (G) of such 2-designs by applying the classification of ...

Wielandt′s Theorem and Finite Groups with Every Non-nilpotent Maximal Subgroup with Prime Index

open access: yesJournal of Harbin University of Science and Technology, 2023
In order to give a further study of the solvability of a finite group in which every non-nilpotent maximal subgroup has prime index, the methods of the proof by contradiction and the counterexample of the smallest order and a theorem of Wielandt on the ...

ON SOME VERTEX-TRANSITIVE DISTANCE-REGULAR ANTIPODAL COVERS OF COMPLETE GRAPHS

open access: yesUral Mathematical Journal, 2022
In the present paper, we classify abelian antipodal distance-regular graphs \(\Gamma\) of diameter 3 with the following property: \((*)\) \(\Gamma\) has a transitive group of automorphisms \(\widetilde{G}\) that induces a primitive almost simple ...

Groups with a Strongly Embedded Subgroup Saturated with Finite Simple Non-abelian Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
An important concept in the theory of finite groups is the concept of a strongly embedded subgroup. The fundamental result on the structure of finite groups with a strongly embedded subgroup belongs to M. Suzuki.

Classification theory of simple locally finite groups

open access: closed, 1983
This thesis constitutes a contribution to applied stability theory. We consider the classification problem of the stable simple locally finite groups. First the classification of the finite simple groups is used to reduce the problem to an identification problem for the simple locally finite groups of Lie type and an interpretation problem in model ...

On matrix representations of oversemigroups of semigroups generated by two mutually annihilating idempotents

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020
Matrix representations of finite semigroups over fields are studied not so well as for finite groups. Representations of finite groups over fields are studied sufficiently well; in particular, the criterions of representation type are fully defined for ...
