Hello everybody, I would like to have some help with these two questions:
1. Let be a finite nilpotent group and a minimal normal subgroup. Show that .
2. Let be a group and verifying non-abelian subnormal subgroups of . Prove that
1. I have already proved that must be abelian; , but I find no way of proving that using that the nilpotency of and each one of its characterizations. Any idea?
Regards and thanks in advance.
