Buckingham's p13 is a period-13 oscillator. It was the first period 13 oscillator to be found, and was discovered by David Buckingham on July 31, 1976.[1] It features two eater 2s used to stabilize another object between them (which is a predecessor of 2 loaves and a bi-boat).
goldenratio found a 37-glider synthesis of this oscillator on July 30, 2020.[2]
