Abstract
Let G be a finite solvable group and Δ be the subset of Υ×Υ, where Υ is the set of all pairs of size two commuting elements in G. If G operates on a transitive G – space by the action (υ1,υ2)g=(υg1,υg2); υ1,υ2∈Υ and g∈G, then orbits of G are called orbitals. The subset Δo={(υ,υ);υ∈Υ,(υ,υ)∈Υ×Υ} represents G′s diagonal orbital.The orbital regular graph is a graph on which G acts regularly on the vertices and the edge set. In this paper, we obtain the orbital regular graphs for some finite solvable groups using a regular action. Furthermore, the number of edges for each of a group’s orbitals is obtained.
如果 G 通过作用 (υ1,υ2)g=(υg1,υg2); υ1,υ2∈Υ 和 g∈G 作用于传递 G - 空间,那么 G 的轨道称为轨道。子集 Δo={(υ,υ);υ∈Υ,(υ,υ)∈Υ×Υ} 表示 G′的对角轨道。轨道正则图是 G 规则地作用于顶点和边集的图。本文利用正则作用得到了一些有限可解群的轨道正则图。此外,我们还得到了每个群轨道的边数。
