Structure of group invariant weighing matrices of small weight
We show that every weighing matrix of weight n invariant under a finite abelian group G can be generated from a subgroup H of G with |H|≤2^(n−1). Furthermore, if n is an odd prime power and a proper circulant weighing matrix of weight n and order v exists, then v≤2^(n−1). We also obtain a lower boun...
