Yes, I guess "parameters of motion" would have been a more appropriate term. So, if I understand correctly, any inverse square interaction will have fewer than 2Nd parameters?

Ordinarily, a system of N particles in d dimensions has 2Nd constants of motion, but there are certain invariants, like energy and angular momentum, that have a lot fewer. What's so special about these? Why do they have so few constants of motion?
