I.B.8

m₃ = 4

From Li & Liao (2017)

I.B.8 m₃ = 4 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 4 that return to their starting positions and velocities every 68.189 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.0000189 of each other at a top speed of 582, line up 204 times a period, and the computed loop closes to 6.5×10⁻¹⁹.
