p-group

• The first part deals with the construction of semisymmetric graphs and the second part classifies the edge - transitive regular coverings of the cube , whose covering transformation groups are iso - morphic to the elementary abelian p - groups
  第一部分是关于半对称图的分类，第二部分是关于立方体边传递的正则覆盖图的分类，其覆盖变换群同构于初等交换p -群。
• With this method , in the present thesis , we will classify all the connected regular covering graphs of the cube satisfying the following two properties : ( 1 ) the covering transformation group is isomorphic to the elementary abelian p - group ; ( 2 ) the group of fibre - preserving automorphisms acts edge - transitively
  本文中，我们用同一种方法分类立方体的正则连通覆盖图，并且满足两个条件，覆盖变换群同构于初等交换p -群且保纤维自同构群是边传递的。
