摘要

我们证明每个可数局部有限群都与$ G$ 的某个正则子群同构。同时，如果 G 的正则子群 H 包含一个无限阶元素，那么 H 有一个有限索引的正则无限循环子群。

On Regular Subgroups in $ \operatorname{Lim}(N) $

Let $ G $ be the group of all limited permutations of the set of naturals. We prove that every countable locally finite group is isomorphic to some regular subgroup of $ G $. Also, if a regular subgroup $ H $ of $ G $ contains an element of infinite order then $ H $ has a normal infinite cyclic subgroup of finite index.
