| Abstract
| - The relationships between inner dual, dualist, sextet dualist, and antisextet dualist graphs and excised internalstructures are fully delineated. It is proven that the antisextet dualist graph uniquely characterizes all strain-free benzenoids. At the same time, it is shown that the excised internal structure and dualist graph of theretro-leapfrog of all strain-free total resonant sextet benzenoids correspond to their antisextet dualist andsextet dualist graphs, respectively.
