The quadpole (or tetrapole) is the barberpole of length 4.
The quadpole is the eighth most common oscillator in Achim Flammenkamp's census, being less common than the bipole but more common than the great on-off. Despite behaving the same in Life as they do in HighLife, they are only about 2% as common.
