本文提出了一种确定长度为40的双偶自对偶极值二元码的陪集重量分布和覆盖半径的方法。该方法本质上是代数的,并且在很大程度上消除了电子计算机的必要计算。该方法很容易适用于较长的代码(例如自对偶[56,28,12]二进制码)或非极值码。
In the present paper we develop a method to determine the coset weight distributions and covering radius of doubly even self-dual extremal binary codes of length 40. The method is algebraic in nature and largely eliminates necessary computations by electronic computers. The method easily applies to longer codes (e.g. self-dual [56,28,12] binary codes) or to non-extremal codes.
