I finished extending the original code in the appendix of my thesis last night.
This particular HGF has its triangular necks with g=0, i.e. there is no carbon atoms ``at'' the neck, with three decagons per neck. And it contains 1260 carbon atoms. However since I didn't actually patch decagons on the molecule, here is the original Matlab .fig file, which may provide a better look of the molecule.
