论文摘要
令$ c $为极端类型III或IV代码,而$ d_ {w} $是$ c $的支持设计。我们介绍了两个数字$δ(c)$和$ s(c)$:$δ(c)$是最大的整数$ t $,因此,对于所有权重,$ d_ {w} $是$ t $ -Design; $ s(c)$表示最大的整数$ t $,因此存在$ w $,因此$ d_ {w} $是$ t $ design。在本文中,我们考虑$δ(c)$和$ s(c)$的可能值。
Let $C$ be an extremal Type III or IV code and $D_{w}$ be the support design of $C$ for a weight $w$. We introduce the two numbers $δ(C)$ and $s(C)$: $δ(C)$ is the largest integer $t$ such that, for all weights, $D_{w}$ is a $t$-design; $s(C)$ denotes the largest integer $t$ such that there exists a $w$ such that $D_{w}$ is a $t$-design. In the present paper, we consider the possible values of $δ(C)$ and $s(C)$.
