Finite groups which are the products of symmetric or alternating groups with $L_3(4)$ [PDF]

International Journal of Group Theory, 2016
In this paper‎, ‎we determine the simple groups $G=AB$‎, ‎where $B$ is isomorphic to $L_{3}(4)$ and $A$ isomorphic to an alternating or a symmetric group on $n\geq5$‎, ‎letters‎.

The Tropical Matrix Groups with Symmetric Idempotents

Discrete Dynamics in Nature and Society, 2018
In this paper we study the semigroup Mn(T) of all n×n tropical matrices under multiplication. We give a description of the tropical matrix groups containing a diagonal block idempotent matrix in which the main diagonal blocks are real matrices and other ...

Automorphism groups of some families of bipartite graphs

Electronic Journal of Graph Theory and Applications, 2021
This paper discusses the automorphism group of a  class of  weakly semiregular bipartite graphs and its subclass called WSBEND graphs.  It also tries to analyse the  automorphism group of the SM sum graphs and SM balancing graphs.

Comparison of Gelfand-Tsetlin Bases for Alternating and Symmetric Groups [PDF]

, 2017
Young's orthogonal basis is a classical basis for an irreducible representation of a symmetric group. This basis happens to be a Gelfand-Tsetlin basis for the chain of symmetric groups. It is well-known that the chain of alternating groups, just like the

Empirical validation of the use of projective techniques in psychological testing using Galois fields

Frontiers in Applied Mathematics and Statistics
It is shown that the problem of the adequacy of psychological testing methods, which are varieties of “projective techniques”, is far from being universally recognized.

Spin characters of generalized symmetric groups

, 2013
In 1911 Schur computed the spin character values of the symmetric group using two important ingredients: the first one later became famously known as the Schur Q-functions and the second one was certain creative construction of the projective characters ...

Subgroups of Infinite Symmetric Groups

Journal of the London Mathematical Society, 1990
Various questions are discussed on the subgroup structure of \(S:=Sym(\Omega)\), where \(\Omega\) is an infinite set. It is shown that S is not the union of a chain of size \(| \Omega |\) of proper subgroups, and results are obtained on the size of the smallest families of proper subgroups with set-theoretic union S.

Symmetric groups and checker triangulated surfaces

, 2017
We consider triangulations of surfaces with edges painted three colors so that edges of each triangle have different colors. Such structures arise as Belyi data (or Grothendieck dessins d'enfant), on the other hand they enumerate pairs of permutations ...
