The mathematician is a period-5 oscillator that was found in 1972 by David Buckingham.[1] A variant of it first appeared semi-naturally in April 2016.[2]
A 99 glider synthesis of this oscillator was found by Inferno on August 2 2021 based on a final step posted by INoMed.[3] Over the next few days, this was reduced by iNoMed, wwei23, MathAndCode, Tanner Jacobi, and Martin Grant to 28 gliders.[4][5]
