Yes, I should have included the clockwise/anti-clockwise route because Muifiield and Kennemer are exactly this, Muirfield having 9 holes routed clockwise on the outside, with 9 holes routed anti-clockwise inside these. Kennemer is the same but the opposite direction. Whereas Lehigh has its front 9 anti-clockwise on the outside, but its back nine doesn't follow a circle.
The clockwise+anticlockwise that isn't internal would be a figure 8, generally?
