摘要
讨论了图K6的电压群为Z4^2的连通拓扑覆盖图,发现图K6没有具有以下条件的连通正则拓扑覆盖图:拓扑覆盖传递群同构于Z4^2;保持束不变自同构子群G2-弧传递的作用于图Г^-.
A new method is used to discuss the connected coverings of graph K6 with the voltage group Z4^2, and we find that there are no 2-transitive regular connected coverings of K6 satisfying the following two conditions : the covering transformation group is isomorphic to Z4^2, andthe fibre-preserving automorphism subgroup acts 2-arc-transitively on the graph Г^- = Г ×ФA.
