Sažetak
A characterization of chemical structures based on counting selfreturning walks in a molecular graph is found to be degenerate for certain pairs of isospectral graphs. On the basis of endospectral graphs, we present (without proof) two theorems for constructing pairs of nonisomorphic graphs with identical atomic counts of self-returning walks.
