Abstract
We examine the cocyclic development of the generalized Sylvester (also
called Drake) Hadamard matrix. In particular, we give detailed results about
the permutation automorphism group and full automorphism group. Following on from this, we derive existence conditions for the indexing and extension groups of each matrix viewed as a cocyclic pairwise combinatorial
design.
