Quadpole tie ship (or quadpole on ship) is a period-2 oscillator composed of a ship diagonally touching a quadpole. A 6-glider synthesis for this oscillator was found in July 2020.^[1]

Commonness

Quadpole on ship is the about the thirteenth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than the mold but more common than tripole.^[2]
