I just noticed that liberties on a go board correspond to the placement of hydrogen atoms on simple alkane hydrocarbons, e.g. n-propane includes eight hydrogen atoms and three go stones placed in a straight line will have eight liberties, the same holds true for any straight chain arrangement. Isopropane would correspond with the empty triangle with seven liberties or seven hydrogens––but isopropane does not exist–– if you were to create isopropanol with an opponents stone representing an oxygen atom then the analogy would stand or an isopropyl moiety with the central carbon/stone attached to an R-group. Cyclobutane includes eight hydrogrens and a square four stone unit (not to be confused with a ponnuki) will have eight liberties. Cyclohexane includes twelve hydrogen atoms and the corresponding six stone ring/eye has twelve liberties. I wonder if the convergence does not end there, could the same factors that define the strength and influence of a go shape impact, say, the stability of a molecule?
