Clock was found by Simon Norton in May 1970. It serves as the logo pattern for WinLifeSearch.
Extensions of the oscillator can be seen as stabilisations for the zebra stripes/chicken wire agar.
Commonness
Clock is the fifth or sixth most common oscillator in Achim Flammenkamp's census, being about as frequent as the pentadecathlon, but much less frequent than the blinker, toad, beacon or pulsar. It is surprisingly rare considering its small size.[1] It is also the sixty-second most common object on Adam P. Goucher's Catagolue.[2]
In other rules
Interestingly, clock can follow three different p2 cycles depending on the rule.
- In rules such as B3/S3, the outer cells oscillate,
- In rules such as B34/S, it evolves into an inverted version of itself and is therefore a phoenix.
