Long barge is an 8-cell still life discovered by the JHC group in 1970.[1] It is a long version of a barge.

It can "eat" two domino sparks, such as those produced by pentadecathlon; said sparks can be replaced with blocks to form unix.


Long barge is the fourteenth most common still life in Achim Flammenkamp's census, being less common than eater 1 but more common than aircraft carrier[2] It is also the nineteenth most common object on Adam P. Goucher's Catagolue.[3]
