#### Abstract

We employ a graphical proof-oriented tool, ZZDecomposer, to discover formal derivations of Zhang-Zhang (ZZ) polynomials for various families and subfamilies of benzenoid structures including tripods, zigzag-edge coronoids fused with a starphene, oblate rectangles , hexagons , , and , and multiple zigzag chains , , , , , and . Current derivations are based… (More)
