Long barge is an 8-cell still life discovered by the JHC group in 1970. It is a long version of a barge. It can be trivially extended to produce ever longer barges.
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 It is also the nineteenth most common object on Adam P. Goucher's Catagolue.
The barge is 7.5 times as common as the long barge, but the long barge is 12,000 times as common as the very long barge.
Since the barge is infinitely extensible, there are an infinite number of long^n barges, one for every positive n:
Very long barge

Long4 barge (or remarkably long barge) is the long^4 version of the barge. It is a 14-bit still life.
Long5 barge (or very4 long barge) is the long^5 version of the barge. It is a 16-bit still life.
Long6 barge (or very5 long barge) is the long^6 version of the barge. It is a 18-bit still life.
