The power graph \({\mathcal {P}}_{G}\) of a finite group G is the graph whose vertex set is G, two distinct vertices are adjacent if one is a power of the other. The order supergraph \({\mathcal {S}}_{G}\) of \({\mathcal {P}}_G\) is the graph with vertex set G, and two distinct vertices x, y are adjacent if o(x)|o(y) or o(y)|o(x). In this paper, we study the independence number of \({\mathcal {S}}_{G}\) and answer a question was posed by Hamzeh and Ashrafi.

关于有限群的幂图的阶主管
有限群G的幂图\({\数学{P}} _ {G} \)是顶点集为G的图,如果一个是另一个的幂,则两个不同的顶点相邻。顺序母图\({\ mathcal {S}} _ {G} \)的\({\ mathcal {P}} _ G ^ \)是与顶点集合的曲线G ^,和两个不同的顶点X, ÿ相邻当ö(x)| o(y)或o(y)| o(x)。在本文中,我们研究\({\ mathcal {S}} _ {G} \)的独立数 并回答了哈姆齐和阿什拉菲的问题。
