Abstract
A survey is presented of the suite of constraints needed to test the ability of the biased cold dark matter (CDM) theory to account for the mass concentrations observed in rich clusters of galaxies. An attempt is made to place limits on the uncertainties in the galaxy clustering length r(0) and the bias parameter b. The limits are favorable but not overly generous for the CDM theory. It is found that no values for r(0) and b are concordant with all available constraints. 72 refs.
