104P9 (or p9 heavyweight emulator[note 1]) is a period-9 oscillator and high-clearance sparker. It was found by wwei23 on November 15, 2020 by combining a known period-9 sparker with a partial result found using JavaLifeSearch.[2]

On December 10, Aidan F. Pierce and "hotdogPi" used this oscillator to construct a p18 R-pentomino shuttle.[3]

Notes

  1. This might be considered a misnomer, as the term "emulator" is sometimes understood to imply period 4.[1]
