A representation is found for the coefficients of the expansion of the one-point correlation function (the one-particle distribution density) in a series in powers of the activity that makes it possible to calculate, at least approximately, the first few coefficients of the expansion. The results can also be used to investigate problems of the thermodynamic limit in the grand canonical ensemble.
