The bipole is the barberpole of length 2 and is thus an oscillator of period 2. It is the smallest possible barberpole.

Commonness

The bipole is the seventh most common oscillator in Achim Flammenkamp's census, being less common than the clock and pentadecathlon but more common than the quadpole.[1]
