The mathematician is a period-5 oscillator that was found in 1972 by David Buckingham.[1][2] A stator variant of it first appeared semi-naturally in April 2016.[3]
A 99-glider synthesis of this oscillator was found by Inferno on August 2, 2021 based on a final step posted by iNoMed.[4] Over the next few days, this was reduced by iNoMed, Aleph, MathAndCode, Tanner Jacobi, and Martin Grant to 28 gliders.[5][6]
Mathematician is by far the period-5 oscillator with the most seminatural stator variants in twofold reflectional odd symmetry, with the only other one coming close being heart which only relies on symmetry to form an induction coil rather than as part of the rotor.
