This paper discusses non lexico extensions of L groups and gives an example of a non abelian lexico extension of an L group,which is not direct but includes a finite number of L ideds,which may contain infinite disjoint elements.

• 讨论了L－群的一个非阿贝尔字典扩张，证得它是非直的。 并且导出一个结论：如果L－群G是非阿贝尔的，虽然仅含有限个L－理想，但是它可以含无限个互斥元
