Abstract

A bound on the 2-rank of an affine designs obtained from a Hadamard design with a line spread via Rahilly's construction is proved and applied to Hadamard designs related to difference sets of GMW type. Some questions motivated by the recent discovery of new counter-examples to the conjectures of A... and Hamada about characterizing geometric designs in terms of their rank are discussed.
