Recall that a complex of abelian groups C• is called perfect if it is quasi- isomorphic to a bounded complex of finitely generated free (= projective) abelian groups. This is the same as asking Hi (C• ) to be finitely generated abelian groups, and Hi (C• ) = 0 for all but finitely many i. In §1.5 we are going to construct certain complexes RΓfg(X, Z(n)) that are almost perfect, in
