Thus 1 ⊴ H ⊴ K ⊴ G is a normal series, as desired.
By Wilson's theorem [11] (hat{G}) possesses a normal series all of whose factors are either p-groups or Cartesian products of isomorphic non-abelian finite simple groups.
By Lemma 2.1, G has a normal series 1 ⊴ N ⊴ G 1 ⊴ G such that N and G / G 1 are π 1 -groups and G 1 / N is a non-abelian simple group, N is a nilpotent group.
Since G is non-solvable, by Lemma 1, we get that G has a normal series 1 ⊴ H ⊴ K ⊴ G such that K / H is a direct product of isomorphic non-abelian simple groups and | G / K | ∣ | Out ( K / H ) |.
Hence H is non-solvable and H has a normal series 1 ⊴ N ⊴ M ⊴ H such that M / N is a direct product of isomorphic non-abelian simple groups and | H / M | ∣ | Out ( M / N ) |.
Then there exists a normal series of H: 1 ⊴ N ⊴ M ⊴ H such that M / N is a direct product of isomorphic non-abelian simple groups and | H / M | ∣ | Out ( M / N ) |.
