The tripole is the barberpole of length 3.
Commonness
The tripole is about the fourteenth most common naturally-occurring 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 7-glider synthesis to 6 gliders on June 23, 2017.[2] goldenratio found a 5-glider synthesis in September 2020.[3]
