The tripole is the barberpole of length 3.
Commonness
The tripole is about the fourteenth most common naturallyoccurring oscillator in Achim Flammenkamp's census, being less common than quadpole on ship but more common than mazing.^{[1]}
Glider synthesis
Martin Grant improved the previous 7glider synthesis to 6 gliders on June 23, 2017.^{[2]}
