Puig Subgroup
In mathematical finite group theory, the Puig subgroup, introduced by , is a characteristic subgroup of a ''p''-group analogous to the Thompson subgroup In mathematical finite group theory, the Thompson subgroup J(P) of a finite ''p''-group ''P'' refers to one of several characteristic subgroups of ''P''. originally defined J(P) to be the subgroup generated by the abelian subgroups of ''P'' of ma .... Definition If ''H'' is a subgroup of a group ''G'', then ''L''''G''(''H'') is the subgroup of ''G'' generated by the abelian subgroups normalized by ''H''. The subgroups ''L''''n'' of ''G'' are defined recursively by *''L''0 is the trivial subgroup *''L''''n''+1 = ''L''''G''(''L''''n'') They have the property that *''L''0 ⊆ ''L''2 ⊆ ''L''4... ⊆ ...''L''5 ⊆ ''L''3 ⊆ ''L''1 The Puig subgroup ''L''(''G'') is the intersection of the subgroups ''L''''n'' for ''n'' odd, and the subgroup ''L''*(''G'') is the union of the subgroups ''L''''n'' for ''n'' even.

Thompson Subgroup
In mathematical finite group theory, the Thompson subgroup J(P) of a finite ''p''-group ''P'' refers to one of several characteristic subgroups of ''P''. originally defined J(P) to be the subgroup generated by the abelian subgroups of ''P'' of maximal rank. More often the Thompson subgroup J(P) is defined to be the subgroup generated by the abelian subgroups of ''P'' of maximal order or the subgroup generated by the elementary abelian subgroups of ''P'' of maximal rank. In general these three subgroups can be different, though they are all called the Thompson subgroup and denoted by J(P).
