The classification of non-solvable transitive BLT-sets of $Q (4, q)$

Weicong Li, Qing Xiang

For an odd prime power $q$ , a BLT-set $B$ is a set of $(q + 1)$ points of $Q (4, q)$ such that every point of $Q (4, q)$ is collinear with at most two points o…

On subgroups of finite classical groups with exactly two orbits on singular or isotropic points

Tao Feng, Qing Xiang

In this paper, we classify the groups of semisimilarities of finite classical polar spaces with exactly two orbits on the singular or isotropic points. As a byproduct, we obtain ma…

A new family of $(q^{4} + 1)$ -tight sets with an automorphism group $F_{4} (q)$

Tao Feng, Weicong Li, Qing Xiang

In this paper, we construct a new family of $(q^{4} + 1)$ -tight sets in $Q (24, q)$ or $Q^{-} (25, q)$ according as $q = 3^{f}$ or $q \equiv 2 (mod 3)$ . The novelty of the construction is the use…
