Let 1 =G,G,... 2G, EG be any series of G whose factors are all nilpotent. Prove that G <F (G) for each i= 0, 1,...,. In particular, the derived length of G is not less than its nilpotent length. (Hint. Argue by induction on i. Note that by 336, every nilpotent subnormal subgroup of a finite group H is contained in F(H).)
