Abstract

In this paper, we prove that there are no nontrivial block-transitive 6-designs for k≤100. This supports the long-standing conjecture of Cameron and Praeger that there are no nontrivial block-transitive 6-designs.

Keywords

Cameron-Praeger conjecture / block-transitive design / affine group / almost simple group
