Trans-beacon on dock is a period-2 oscillator composed of a beacon stabilizing a dock. A 5-glider synthesis for this oscillator was found in January 2020.[1]


Trans-beacon on dock is about the thirtieth most common naturally-occurring oscillator in Achim Flammenkamp's census, being slightly less common than tub test tube baby and more common than cis-beacon up on long hook.[2]
