Abstract:Many different divisible designs are already known. Some of them possess remarkable automorphism groups, so called dual translation groups. The existence of such an automorphism group enables us to characterize its associated divisible design as being isomorphic to a substructure of a finite affine space.
“…Also, we refer to [120] for a discussion of transitive extensions of imprimitive groups. A generalisation of Spera's construction was exhibited in [54] and [56]. It was put into a more general context in [38] as follows: Let a group G acting on some set X and a starter t-DD in X be given.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
