This paper offers a unified, research-level treatment of the interaction between graph-theoretic invariants and the normal subgroup structure of graph automorphism groups. Starting from the classical framework of Frucht, Sabidussi, Whitney and Watkins, we develop the analysis of as a permutation group through three complementary lenses: (i) the ...

Hypermaps Over Non-Abelian Simple Groups and Strongly Symmetric Generating Sets [PDF]
A generating pair x, y for a group G is said to be symmetric if there exists an automorphism φx,y of G inverting both x and y, that is, xφx,y = x−1 and yφx,y = y−1.

On Semisymmetric Cubic Graphs of Order 20p2, p Prime
A simple graph is called semisymmetric if it is regular and edge-transitive but not vertex-transitive. Let p be an arbitrary prime. Folkman proved [Regular line-symmetric graphs, J. Combin. Theory 3 (1967) 215–232] that there is no semisymmetric graph of

We give a lattice theoretical interpretation of generalized deep holes of the Leech lattice VOA $V_\Lambda $ . We show that a generalized deep hole defines a ‘true’ automorphism invariant deep hole of the Leech lattice. We also show that there is a

A question of Frohardt on $2$ -groups, skew translation quadrangles of even order and cyclic STGQs
We solve a fundamental question posed in Frohardt’s 1988 paper [6] on finite $2$ -groups with Kantor familes, by showing that finite groups K with a Kantor family $(\mathcal {F},\mathcal {F}^*)$ having distinct members $A, B \in \mathcal

RESPONSE OF BREAD WHEAT TO INCREASING. MUSTARD MEAL NITROGEN APPUCATION ON PELLIC VERTISOL AND EUTRIC NITOSOL [PDF]
Mustard seed meal was evaluated on the field as source of nitrogen for bread wheat on Pellic Vertisol and Eutric Nitosol in a split plot design with three replications.

Boolean lattices in finite alternating and symmetric groups
Given a group G and a subgroup H, we let $\mathcal {O}_G(H)$ denote the lattice of subgroups of G containing H. This article provides a classification of the subgroups H of G such that $\mathcal {O}_{G}(H)$ is Boolean of rank at least

Pentavalent arc-transitive Cayley graphs on Frobenius groups with soluble vertex stabilizer
A Cayley graph Γ is said to be arc-transitive if its full automorphism group AutΓ is transitive on the arc set of Γ. In this paper we give a characterization of pentavalent arc-transitive Cayley graphs on a class of Frobenius groups with soluble vertex ...

A characterization of the desarguesian planes of order q2 by SL(2, q)
The main result is that if the translation complement of a translation plane of order q2 contains a group isomorphic to SL(2, q) and if the subgroups of order q are elations (shears), then the plane is Desarguesian. This generalizes earlier work of Walker, who assumed that the kernel of the plane contained GF(q).

Translation planes of even order in which the dimension has only one odd factor
Let G be an irreducible subgroup of the linear translation complement of a finite translation plane of order qd where q is a power of 2. GF(q) is in the kernel and d = 2sr where r is an odd prime. A prime factor of |G| must divide . One possibility (there are no known examples) is that G has a normal subgroup W which is a W‐group for some prime W.
