The tumbler is the smallest known and first discovered period-14 oscillator and was found by George Collins in 1970.[1][2] It was the only known period 14 oscillator until the discovery of 44P14 on April 21, 1997.
Use as a sparker
The tumbler has a few, but very few, applications where it can act as a weak sparker. In most cases, the tumbler is not the only thing that works, but it can be useful to reduce the population.
Tumbler on Rich's p16, the smallest known p112 oscillator by population (click above to open LifeViewer) RLE: here Plaintext: here |
Tumbler is about the twenty-eighth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than octagon 2 and unix but more common than tub test tube baby.[5] On Catagolue, it is the only known period 14 oscillator to have occurred naturally.[6]
In August 2014, Bob Shemyakin found a 6-glider synthesis[7] for a tumbler. In January 2020 Tanner Jacobi found a cheaper recipe with a Catagolue-based randomized 5-glider search.[8]
