Abstract: 本文中我們首先定義覆蓋圖形,然後利用其性質證明可以找到無限多個線遞移,或t-遞移或局部t-遞移圖形。
N. Biggs [1] proved that if G is a t-transitive graph, then there exists a covering graph which is also t-transitive. In this paper, we extend this result to local t-transitivity and to edge-transitivity.Let G be a graph, the group of graph-automorphism of G will be denoted by aut(G).V(G) and E(G) denote the sets of vertices and edges of G, respectively. In this paper, we assume that G is simple, that is, G has no Multiple edges and no loops.
