Hamming图中的逃逸码

Elusive Codes in Hamming Graphs

Daniel R. Hawtin, Neil I. Gillespie, Cheryl E. Praeger

摘要:

我们认为一个码是一个汉明图的顶点集的子集。我们研究难以捉摸的对,代码组对的代码是不确定的知识,它的邻居。我们构建了一个新的无限家庭的难以捉摸的对,在那里的问题组的行为传递的邻居的代码。在我们的例子中,我们发现,字母表的大小总是划分的代码的长度,并证明,没有难以捉摸的对最小的参数集,这是不是这种情况。我们还提出了几个问题,关于难以捉摸的对。

英文摘要:

We consider a code to be a subset of the vertex set of a Hamming graph. We examine elusive pairs, code-group pairs where the code is not determined by knowledge of its set of neighbours. We construct a new infinite family of elusive pairs, where the group in question acts transitively on the set of neighbours of the code. In our examples, we find that the alphabet size always divides the length of the code, and prove that there is no elusive pair for the smallest set of parameters for which this is not the case. We also pose several questions regarding elusive pairs.
