Normal subgroup of finite index
WebMoreover, G has an abelian normal subgroup of index bounded in terms of n only. In [2], Lennox, Smith and Wiegold show that, for p 6= 2, a core-p p-group is nilpotent of class at most 3 and has an abelian normal subgroup of index at most p5. Furthermore, Cutolo, Khukhro, Lennox, Wiegold, Rinauro and Smith [3] prove that a core-p p-group G Web31 de mar. de 2024 · Let’s begin this post with a well-known result about the normality of subgroups of prime index.

It follows from an important result of Obraztsov [] that X can be embedded into a periodic simple group G in which every proper non-abelian subgroup is isomorphic to a subgroup of X.Therefore all proper subgroups of G are quasihamiltonian-by-finite, and G is not …
WebFINITELY GENERATED SUBGROUPS OF FINITE INDEX 23 A generalization of this result, proved in [7], is the following: If G—(A * B; U) where U is finite and A^U^B, and if H is a f.g. subgroup containing a normal subgroup of G not contained in U, then H is of f.i. in G ; in particular, if U contains no subgroup normal in both A and B, WebExpert Answer. Transcribed image text: 13. If a group G contains a subgroup (# G) of finite index, it contains a normal sub- group (G) of finite index. 14. If G = pn, with p > n, p prime, and H is a subgroup of order p, then H is normal in G. 15. If a normal subgroup N of order p (p prime) is contained in a group G of order p", then N is in ...

Webin its normal closure, then G is finite-by-abelian, and so the index of each subgroup in its normal closure is bounded. In this paper we shall be concerned with a dual property. We shall say that a group G is a CF-group (core-finite) if each of its subgroups is normal-by-finite, that is, if H/ coreG(//) i finites for all subgroups H of G. That such
