Generalised Paley graphs with a product structure
Geoffrey Pearce, Cheryl E Praeger
A graph is Cartesian decomposable if it is isomorphic to a Cartesian product of (more than one) strictly smaller graphs, each of which has more than one vertex and admits no such d…
A normal quotient analysis for some families of oriented four-valent graphs
Jehan A. Al-bar, Ahmad N. Al-kenani, Najat Mohammad Muthana +1
We analyse the normal quotient structure of several infinite families of finite connected edge-transitive, four-valent oriented graphs. These families were singled out by Marusic a…
Finite edge-transitive oriented graphs of valency four with cyclic normal quotients
Jehan A. Al-bar, Ahmad N. Al-kenani, Najat Mohammad Muthana +1
We study finite four-valent graphs Gamma admitting an edge-transitive group G of automorphisms such that G determines and preserves an edge-orientation on Gamma, and such that at l…
Group factorisations, uniform automorphisms, and permutation groups of simple diagonal type
Cheryl E. Praeger, Csaba Schneider
We present a new proof, which is independent of the finite simple group classification and applies also to infinite groups, that quasiprimitive permutation groups of simple diagona…
Twisted Centralizer Codes
Adel Alahmadi, S. P. Glasby, Cheryl E. Praeger +2
Given an matrix over a field and a scalar , we consider the linear codes of length . We call …
On the dimension of twisted centralizer codes
S. P. Glasby, Cheryl E. Praeger, Adel Alahmadi
Given a field , a scalar and a matrix , the twisted centralizer code is a linear code of length $n^2…
