Unix (plural: unices) is a period 6 oscillator that was found by David Buckingham on February 10, 1976. It consists of two blocks eating a long barge and is a useful sparker.[1] Its name derives from the fact that it was for some time the mascot of the Unix lab of the mathematics faculty at the University of Waterloo in Ontario, Canada. With just 16 cells, it is the smallest known period 6 oscillator.[2]

Commonness

Unix is about the twenty-sixth most common naturally-occurring oscillator in Achim Flammenkamp's census, being about as common as octagon 2.[3] On Catagolue, it is the most common period 6 oscillator and the only non-trivial one to have appeared naturally, as all others consist of period 2 and 3 rotors that do not interact.[4]
