报告摘要:
A combinatorial block design D is called 3-pyramidal if there exists a subgroup G of Aut(D) fixing 3 points and acting regularly on the other points. If this happens, we say that the design is 3-pyramidal under G. If D is a Kirkman Triple System, it is known that such a group G has precisely 3 involutions, all conjugate to each other. In this talk, we will discuss the groups with this property.
