This thesis is concerned with the study of Delsarte designs in symmetric association
schemes, particularly in the context of finite geometry. We construct an infinite family of …

We investigate intriguing sets of an association scheme introduced by Penttila and Williford
(2011) that was the basis for their construction of primitive cometric association schemes that …

Although many abstractions of hemisystems of H (3, q 2) have been introduced since the first
infinite family was discovered by Cossidente and Penttila in 2005, none have been applied …
