	THE SCHUR–ZASSENHAUS THEOREM KEITH CONRAD When N is a normal subgroup of G, can we reconstruct G from N and G/N ? In general, no. For instance, the groups Z/(p2 ) and Z/(p) × Z/(p) (for prime p) are nonisomorphic, but DocID: 1vr1L - View Document
	SUBGROUP SERIES I KEITH CONRAD 1. Introduction If N is a nontrivial proper normal subgroup of a finite group G then N and G/N are smaller than G. While it is false that G can be completely reconstructed from knowledge DocID: 1v04a - View Document
	SUBGROUP SERIES II KEITH CONRAD 1. Introduction In part I, we met nilpotent and solvable groups, defined in terms of normal series. Recalling the definitions, a group G is called nilpotent if it admits a normal series (1 DocID: 1ucTI - View Document
