存在188阶和388阶的斜阿达玛矩阵

Skew-Hadamard matrices of orders 188 and 388 exist

Dragomir Z. Djokovic

摘要:

我们在47阶和97阶循环群上构造了几个差族,并利用它们构造了188阶和388阶的斜阿达玛矩阵。这种差分族和矩阵的构造在这里是第一次。这些矩阵是通过使用Goethals-Seidel数组构造的。

英文摘要:

We construct several difference families on cyclic groups of orders 47 and 97, and use them to construct skew-Hadamard matrices of orders 188 and 388. Such difference families and matrices are constructed here for the first time. The matrices are constructed by using the Goethals-Seidel array.
