They're not sending their best problems folks.

It's obvious there are sub-cycles in it otherwise it is inane. I decided in a couple mins there were smaller repeating patterns otherwise it is intractable. This is part of the issue I had with some of the problems in 2018.

It doesn't use any techniques of optimizing an actual N-body problem with large numbers of bodies like distance approximations, gridding, etc... This is more like a "gears" application of LCM.
