On an inequivalence criterion for cocyclic Hadamard matrices
(Springer, 2010)
Given two Hadamard matrices of the same order, it can be quite difficult to decide whether or not they are equivalent. There are some criteria to determine Hadamard inequivalence. Among them, one of the most commonly ...

Embedding cocylic D-optimal designs in cocylic Hadamard matrices
(International Linear Algebra Society, 2012)
A method for embedding cocyclic submatrices with “large” determinants of orders 2t in certain cocyclic Hadamard matrices of orders 4t is described (t an odd integer). If these determinants attain the largest possible ...
