Sažetak

An algorithm for computing the algebraic structure count in polygraphs is presented. It expresses the related determinant of the adjacency matrix of a polygraph in terms of the determinants of monographs and bonding edges between the monographs. The algorithm is illustrated on a class of polygraphs with two bonding edges between monographs and computations for selected examples of polygraphs of this class are presented.
