Let M be a closed, connected, orientable topological 4" role="presentation" >4-manifold, and G be a finite group acting topologically and locally linearly on M. In this paper, we investigate the spectral sequence for the Borel cohomology HG∗(M)" role="presentation" >HG(M) and establish new bounds on the rank of G for homologically trivial actions with discrete singular set.
