利用GF(5)上的线性码构造了Z ~ 2 × Z ~ 2 × Z ~(45)上的可逆交换Hadamard差集.这是第一个例子的阿贝尔阿达玛差集在一个组的顺序整除的素数?1(mod 4)。应用Turyn复合定理,得到了4× 54 n × p4 n11 ×?×p4nttwheren,n1,?,numerous任意非负整数和eachpi是一个素数,pi?3(mod 4)。
Linear codes overGF(5) are utilized for the construction of a reversible abelian Hadamard difference set inZ2×Z2×Z45. This is the first example of an abelian Hadamard difference set in a group of order divisible by a primep?1 (mod 4). Applying the Turyn composition theorem, one obtains abelian difference sets and Hadamard matrices of Williamson type of order 4×54n×p4n11×?×p4nttwheren, n1, ?, ntare arbitrary non-negative integers and eachpiis a prime,pi?3 (mod 4).
