Abstract

This paper studies the set of finite groups appearing as π1(M)π1(M)(n), where M is a closed, orientable 3–manifold and π1(M)(n) denotes the nth term of the derived series of π1(M). Our main result is that if M is a closed, orientable 3–manifold, n2, and Gπ1(M)π1(M)(n) is finite, then the cup-product pairing H2(G)H2(G)H4(G) has cyclic image C, and the pairing H2(G)H2(G)C is isomorphic to the linking pairing H1(M) TorsH1(M) Tors.
