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]}
A 5glider synthesis of this oscillator was found by Goldtiger997 on May 14, 2019, based on a 4glider collision submitted to Catagolue by Arie Paap in a custom apgsearch symmetry.^{[3]}
Commonness
Unix is about the twentysixth most common naturallyoccurring oscillator in Achim Flammenkamp's census, being about as common as octagon 2.^{[4]} On Catagolue, it is the most common period 6 oscillator and the only nontrivial one to have appeared naturally, as all others consist of period 2 and 3 rotors that do not interact.^{[5]}
