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.

Commonness

Barge is the tenth most common still life on Adam P. Goucher's Catagolue, being less common than ship-tie but more common than half-bakery. Among all still lifes with 6 cells, it is the third most common, being less common than ship but more common than aircraft carrier.[2] It is also the fourteenth most common object overall on Catagolue.

In Achim Flammenkamp's census, the barge was also ranked tenth most common, again between the ship-tie and half-bakery.[3]

Glider synthesis

All strict still lifes with a population of 20 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.

Extensibility

Barge can be infinitely extended, as illustrated by the following:
