Achim's p11 is a period 11 oscillator discovered by Achim Flammenkamp on August 4, 1994.^{[1]} In February, 2000 Mark Niemiec created a 96glider synthesis for this oscillator.^{[2]} It was later improved to 75 gliders by Jeremy Tan on July 11, 2019,^{[3]} followed by 63 gliders due to improvements by Matti Ward and toroidalet later the same day.^{[4]}^{[5]}
