Abstract
It is known for some time that closed 4-manifolds provide,
via the fundamental group and the Euler characteristic,
interesting invariants for finitely presented groups. In this
survey I describe these and more refined invariants and
mention some of their significance both for the manifolds
and the groups. The invariants are not easily computed but
some information is obtained using modern tools.
