A Note on Subgroup Perfect Codes in Cayley Graphs
Li JingjianLi BinbinLiu Xianglin
文献摘要
In this paper, we give a necessary and sufficient condition for a subgroup to be a perfect code for finite groups. As an application, we determine all subgroup perfect codes of extraspecial 2-groups and finite groups whose Sylow 2-subgroup is extraspecial.
