The circular altitude of a graph
John Bamberg, Brian Corr, Alice Devillers +3
In this paper we investigate a parameter of graphs, called the circular altitude, introduced by Peter Cameron. We show that the circular altitude provides a lower bound on the circ…

An -cover of the Hermitian surface of is a set of lines of such that every point of lies on exactly lines of $\mat…
Point-primitive generalised hexagons and octagons
John Bamberg, S. P. Glasby, Tomasz Popiel +2
In 2008, Schneider and Van Maldeghem proved that if a group acts flag-transitively, point-primitively, and line-primitively on a generalised hexagon or generalised octagon, then it…
An enumeration of certain projective ternary two-weight codes and their relationship to the cubic Segre variety
Michael Martis, John Bamberg, Sylvia Morris
We detail the enumeration of all two-intersection sets of the five-dimensional projective space over the field of order 3 that are invariant under an element of order 7, which incl…
