Abstract:

It has already been shown, using a combinatorial argument, that a Hadamard design with each letter repeated once and only once can exist for 2, 4 and 8 letters only. In this paper the same result is proved by a different method which utilizes the underlying algebraic structure of such a Hadamard design.
