Conjecture on main simple choreographies in the equal mass Newtonian N-body problem

Let N3N\geq 3 and consider the equal mass Newtonian NN-body problem. A main simple choreography is a simple choreography that is not derived from a given simple choreography by traveling around it multiple times, by a continuation of the angular momentum, or by a combination of both. The trivial circle solution is the rotating NN-gon.

Main choreography conjecture. For every N3N\geq 3, there is a main simple choreography solution different from the trivial circle solution. The number of such distinct main simple choreographies grows rapidly with NN.

This conjecture arises from numerical discoveries and predicts that the Newtonian problem has many genuinely distinct simple choreographies beyond the rotating NN-gon. The supplied text does not state a resolution, so its status remains open.
