This article is about the 6-cell still life. For the extensible c/3 spaceship, see Barge (spaceship).

The barge is a common 6-cell still life discovered by the JHC group in 1970.[1] It is infinitely extensible, and can be seen as a long version of the tub.


Barge is the tenth most common still life in Achim Flammenkamp's census, being less common than ship-tie but more common than half-bakery.[2] It is also the fourteenth most common object on Adam P. Goucher's Catagolue. It is the third most common 6-bit still life, being less common than the ship but more common than the aircraft carrier.[3]
