Summary: The generating function for calculating closed self-avoiding diagrams on the honeycomb lattice is constructed and its thermodynamic limit found. The presence of a phase transition in the system is noted, and the critical value of the interaction constant is found. The calculations are made by means of integration with respect to anticommuting variables.
