Abstract In this paper, we prove that the minimum size of a hypergroup of type U on the right which contains a proper subsemihypergroup of type U on the right of size 6 and a subgroup of size is 18. We study some properties of hypergroups of type U on the right of size 2p that have a cyclic subgroup of size p. Moreover, we give a more general answer to a problem left open in [11].

关于右侧 U 型超群中最小尺寸的进一步性质

摘要 在本文中,我们证明了在右边包含一个大小为 6 的 U 类型的适当子半超群和一个大小为 18 的子群的右边 U 类型超群的最小大小为 18。我们研究了类型超群的一些性质大小为 2p 右侧的 U 具有大小为 p 的循环子群。此外,我们对 [11] 中未解决的问题给出了更一般的答案。
