104P9 (or p9 heavyweight emulator^{[note 1]}) is a period9 oscillator and highclearance sparker. It was found by wwei23 on November 15, 2020 by combining 50P9 with a partial result found using JavaLifeSearch.^{[2]}
On December 10, praosylen and David Raucci used this oscillator to construct a p18 Rpentomino shuttle.^{[3]} Raucci then used it in a p63 skewed pulsar hassler on July 19, 2021,^{[4]} and a smaller period54 glider gun on September 16, 2021.^{[5]}
