- For the class of patterns sometimes called ships, see spaceship.
Ship is a 6-bit still life. It was discovered by the JHC group in 1970.[1] It is the smallest pattern that is a still life under the standard Life rules but not in HighLife.
Adding one cell to the corner of the ship will turn it into a fleet.
Ship can act as an eater, eating one half of a traffic light.
Commonness
The ship is the seventh most common still life in Achim Flammenkamp's census, being less common than pond and more common than long boat.[2] It is also the seventh most common object on Adam P. Goucher's Catagolue.[3]
