中文摘要:
如果 G 有合适的正常亚群 N ,有限的组 G 被称为一个 Camina 组以便 gN 正是为任何 g G-N.In 的 G 的一个 conjugacy 班这份报纸, Camina 组 G 的结构被决定 N 是否是 G 的 2,3 或 4 个 conjugacy 班的一个工会。
英文摘要:
A finite group G is called a Camina group if G has a proper normal subgroup N such that gN is precisely a conjugacy class of G for any g ∈E G - N. In this paper, the structure of a Camina group G is determined when N is a union of 2, 3 or 4 conjugacy classes of G.
