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. Removing one of the corner cells results in a boat, while removing both results in a tub. Like the tub and the boat, it is infinitely extensible (see long ship).

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. It is the second most common 6-bit still life, being less common than the beehive but more common than the barge.[3] It is the most common object in Catagolue for which no 2-glider synthesis is known.
