Yves, "transposition" should read contrgradient ($X\mapsto (X^t)^{-1}$). Also, $\mbox{Aut}(Z(G))$ should read $\mbox{Aut}(G/Z(G))$.

comment Is the free abstract group residually of rank d > 2?
This rank was introduced by Malcev and is called special rank. Namely, The special rank of a group $G$ is the minimal $d$ such that every finitely generated subgroup of $G$ can be generated by $d$ elements.

Actually, their theorem states this under some cardinality constraints: gdz.sub.uni-goettingen.de/…
