Abstract
For a diagram group G, the first derived quotient G(1)/G(2) is always free abelian (as proved by M. Sapir and V. Guba). However the second derived quotient G(2)/G(3) may contain torsion. In fact, we show that for any finite or countably infinite direct product of cyclic groups A, there is a diagram group with second derived quotient A. We use that to construct families with the properties of the title.
