有限群α(G)表示图X的最小顶点数,其自同构群A(X)与G同构。Sabidussi证明了[1],其中n=G,d是G的最小生成元数。由于0(Logn)是d的最佳可能上界,文[1]中建立的结果暗示了α(G)=0(Nloglogn)。
For G a, finite group let α(G) denote the minimum number of vertices of the graphs X the automorphism group A(X) of which is isomorphic to G. G. Sabidussi proved [1], that α(G)=0(n log d) where n=G and d is the minimum number of generators of G.As 0(log n) is the best possible upper bound for d, the result established in [1] implies that α(G)=0(n log log n).
