It is good to observe why ss and sn did not effect ordinals in FGH so well, while nn did. Although ss and sn are sufficiently complicated nestings, these types of nestings are actually weaker than FGH. On the other hand, nn is both simple and strong compared to them. I note that FGH is even stronger than nn.
