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. 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. iNoMed reduced this to 32 gliders on April 5, 2021.
