The tumbler is the smallest known and first discovered period 14 oscillator and was found by George Collins in 1970.[1] It is about the twenty-eighth most common naturally-occurring oscillator, being less common than octagon 2 and unix but more common than tub test tube baby.[2] This was the only known period 14 oscillator until the discovery of 44P14 on April 21, 1997.
In November 2014, Aidan F. Pierce found a predecessor for this pattern based on a soup from Adam P. Goucher's apgsearch script, which allowed for a 6-glider synthesis.[3]
