In this paper, we show that exactly one Hadamard matrix constructed using the twin prime power method is cocyclic. We achieve… (More)
To any complex Hadamard matrix H one associates a spin model commuting square, and therefore a hyperfinite subfactor. The… (More)

We show that a family of cyclic Hadamard designs defined from regular ovals is a sub-family of a class of difference set designs… (More)
