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).

In August 2013, Martin Grant found a 116-glider synthesis for a variant of this oscillator using different eater 2s,[2] and Mark Niemiec made a 113-glider synthesis for the canonical form shown in infobox.[3] Later, goldenratio found a 37-glider synthesis of this oscillator on July 30, 2020.[4] iNoMed reduced this to 32 gliders on April 5, 2021.[5]
