Abstract
We present an update on the study of topological structure of QCD. Issues addressed include a comparison between the plaquette and the geometric methods of calculating the topological density. We show that the improved gauge action based on {radical}(3) blocking transformation suppresses the formation of topologically charged dislocations with low action. Using a cooling method we identify the instantons` location, estimate their size and density, and calculate the renormalization constant Z{sub Q} for the plaquette method. ((orig.)).
