We classify all linear completely regular codes which have covering radius \(\rho=2\) and whose dual are antipodal. For this, we firstly show several properties of such dual codes, which are two-weight codes with weights \(d\) and \(n\).

覆盖半径为二且对偶的完全正则码的分类

我们对所有具有覆盖半径\(\rho=2\)且对偶对映的线性完全正则码进行分类。为此，我们首先展示这种对偶码的几个属性，它们是具有权重\(d\)和\(n\)的双权重码。
