Nonexistence of two circulant weighing matrices of weight 81
In this paper, we prove the nonexistence of two weighing matrices of weight 81, namely CW(88,81) and CW(99,81) . We will apply two very different methods to do so; for the case of CW(88,81) , we will use almost purely counting methods, while for CW(99,81) , we will use algebra...
