摘要: 给出了构造码长为38的具有3-(12,2)型自同构的二元 自对偶极值码生成矩阵算法, 并通过运行Visual C++程序, 首次得到了这样的极值码, 判定新构造码的重量计数子是W2.

关键词: 二元自对偶极值码, 自同构, 重量计数子

Abstract: The present paper presented an algrithom to find generator matrices of extremal selfdual binary codes of length 38 with the automorphisms of type 3-(12,2). By implementing Visual C++ procedures, we obtained such new extremal codes and determined the codes to meet the weight enumerator W2.

Key words: extremal selfdual binary code, automorphism, weight enumerator
