- 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. 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.
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. 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. It is the most common object in Catagolue for which there is no 2-glider synthesis.
The ship is about 4.5 times as common in Catagolue than in Achim Flammenkamp's census; it is more common than the tub and the pond in the former but not the latter. The reason for this huge discrepancy is because Catagolue's soups are 16×16 with empty space surrounding it, and a Herschel leaving the active region and going into the empty space produces a ship. In comparison, Achim Flammenkamp's census is on a large torus, which is effectively an infinite region, so there is no empty space for a Herschel to complete its sequence, and it is likely to crash into something first.
