Abstract: A proof is given for a generalization of a theorem of Mennicke that each member of a certain family of groups defined by generators and relations is finite. This leads to the following theorem on factorization of groups.

Theorem. Let G be generated by abelian subgroups A, B, C, such that $ [A,B] \leqslant A,[B,C] \leqslant B,[C,A] \leqslant C$; then the second derived group, $ G''$ is nilpotent of class at most 3.

Also proved is the analogue of the above theorem for Lie algebras.
