Post holes are useless, because you can split left and then split back to the right. So all you need are the n tokens. Hanoi isn't a good model for this, because the posts are not fixed in place and the units are all identical. It's a bad physical game because the player has to do all the work to enforce the rules. The environment doesn't provide any useful assistance.
