Apart from being an interesting and exciting area in combinatorics with beautiful results,
finite projective spaces or Galois geometries have many applications to coding theory …

A code ${\mathcal C} $ is a subset of the vertex set of a Hamming graph $ H (n, q) $, and
${\mathcal C} $ is $2 $-neighbour-transitive if the automorphism group $ G={\rm …

In this article we are interested in characterization theorems of the point sets of classical
objects such as conics, quadrics, Hermitian varieties and (Baer) subgeometries in terms of …

Imagine a geometry (P, L) of points and lines. It is said to admit a Singer group (wrt points) if
there is a group G of automorphisms which acts freely and transitively (= sharply transitively …
