Construction Rules
Take points uniformly distributed on a circle.
Connect them in the given order using an arc of the circle that intersects the original circle perpendicularly.
The resulting curve must be smooth and closed.
Circles with infinite radius are drawn as lines.
For even numbers start with the inner arc.
For odd numbers, a non-smooth singularity is allowed. The direction of the curve is then determined by the sign + or -, indicating whether the first arc is the inner or outer arc.
