摘要
在(Striker in Discret Math Theor Comput Sci 20, 2018)一文中,Striker 广义了 Cameron 和 Fon-Der-Flaass 的拨动群概念。在本文中,我们开始研究包含一个循环的传递广义拨动群。我们首先证明,如果这样一个群的度数为 n,并且包含一个转置或一个 3 循环,那么这个群就包含 \(A_n\)。利用关于转置的结果,我们证明了包含短循环的广义肘旋群一定是原始群。利用琼斯(Bull Aust Math Soc 89(1):159-165,2014)的一个结果(该结果依赖于有限简单群的分类),我们得出结论:任何包含至少 3 个固定点的循环的 n 度传递广义拨动群也必须包含 \(A_n\)。最后,我们研究了包含一个长周期的imprimitive广义拨动群,并证明它们分解为原始广义拨动群的直接乘积,每个原始广义拨动群都包含一个长周期。
Transitive generalized toggle groups containing a cycle
In (Striker in Discret Math Theor Comput Sci 20, 2018), Striker generalized Cameron and Fon-Der-Flaass’s notion of a toggle group. In this paper, we begin the study of transitive generalized toggle groups that contain a cycle. We first show that if such a group has degree n and contains a transposition or a 3-cycle, then the group contains \(A_n\). Using the result about transpositions, we then prove that a transitive generalized toggle group that contains a short cycle must be primitive. Employing a result of Jones (Bull Aust Math Soc 89(1):159-165, 2014), which relies on the classification of the finite simple groups, we conclude that any transitive generalized toggle group of degree n that contains a cycle with at least 3 fixed points must also contain \(A_n\). Finally, we look at imprimitive generalized toggle groups containing a long cycle and show that they decompose into a direct product of primitive generalized toggle groups each containing a long cycle.
