Abstract. A B(2)-group is a sum of finitely many torsionfree Abelian groups of rank 1, subject to two independent relations. We study here a particular kind of decomposition, that mimics the general case for B(1)-groups; we give necessary and sufficient conditions for it in two out of three cases, and a counterexample in the third.
