Flag-transitive point-primitive quasi-symmetric $2$-designs with block intersection numbers $0$ and $y\le 10$

Jianbing Lu, Yu Zhuang

In this paper, we show that for a non-trivial quasi-symmetric $2$-design $\mathcal{D}$ with two block intersection numbers $x=0$ and $2\le y\le 10$, if $G\leq \mathrm{Aut}(\mathca…
