Ship

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.

Pattern type Strict still life
Number of cells 6
Bounding box 3×3
Frequency class 3.3
Discovered by JHC group
Year of discovery 1970
For the class of patterns sometimes called ships, see spaceship.

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.

gollark: It might be.
gollark: Between what and what?
gollark: Birds sometimes stand on things sideways.
gollark: I assume the bar was just curved before the bird got there.
gollark: In what way?
