: The authors used a supercomputer and a strategy called "Clean Numerical Simulation" to overcome the "butterfly effect" (rounding errors) in calculations.

: The "z" prefix typically refers to the collisionless nature of these orbits, while "12" identifies this specific complex, figure-eight-like pattern. ⚛️ Why This Matters

: The .7z file is part of a larger database containing 1,223 new families of periodic orbits found using the Clean Numerical Simulation (CNS) method.

: The data originates from the landmark paper "Three-body problem - from Newton to supercomputer plus machine learning" by physicists XiaoMing Li and ShiJun Liao (2017).
