Annotation
A many-particle model problem with four-fermian positive interaction and sources is considered. Asymptotically exact expressions were obtained for the free energy and many-term coalition functions. It is shown that the role of the interaction reduces to renormalization (weakening) of the sources in the thermodynamic limit.
