From Three Body Orbits (2026)

AAABabABaBAbABaBAbaB (1.12, 0.923, 0.88) is a periodic orbit of the planar three-body problem: three masses in the ratio 1.12 : 0.923 : 0.88 that return to their starting positions and velocities every 14.31 time units, published by Three Body Orbits (2026). Forty-two periodic orbits of topologies absent from the checked catalogues, found in a September 2026 search at unequal masses: the middle body lighter or heavier than the outer two, or all three different. Each is named by its free-group word, a few by a nickname; all are unstable. Candidate new families relative to the catalogues checked, not established discoveries. It is unstable (largest Floquet multiplier 463.1), so a small nudge makes it unravel over a few periods. The bodies pass within 0.113 of each other at a top speed of 3.48, line up 32 times a period, and the computed loop closes to 2.0×10⁻²⁸. The search, its checks and the catalogue comparison are in the research note.
