Some properties of the inertia groups of Boolean bijunctive functions, and an injunctive method for the generation of such functions

The class of bijunctive Boolean functions consists of the functions representable by the 2-CNF\@. The problem of enumeration of such function of arbitrary number of variables has not been solved. In the paper, we consider properties of inertia groups of bijunctive functions in several groups and give an inductive method of generating all distinct representatives of the classes of geometric equivalence of bijunctive functions. By this method we calculate the numbers of bijunctive functions of 5, 6, and 7 variables.
