The tumbler is the smallest known and first discovered period 14 oscillator and was found by George Collins in 1970.^{[1]} It was the only known period 14 oscillator until the discovery of 44P14 on April 21, 1997.
Commonness
Tumbler is about the twentyeighth most common naturallyoccurring oscillator in Achim Flammenkamp's census, being less common than octagon 2 and unix but more common than tub test tube baby.^{[2]}
Synthesis
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 6glider synthesis.^{[3]}
