While not part of the puzzle, but having a bit to do with why it was created in the first place.. an interesting exercise  no reward other than knowledge though I'll probably put a pi with a randomizied python script on it. finding a collision for the first two in the puzzle and see how far apart they are, might give a "clearer view" of the curve if that makes any sense. - Though that would probably end up being harder than finding #160 - Still, worth thinking about.
