Very long barge (or long long barge) is a barge that is extended by a length of two. This can be repeated to make a long^3 barge, long^4 barge, and so on.
Commonness
The very long barge is extremely rare compared to the long barge, by a factor of 12,000. This is in contrast to the regular barge versus the long barge (7.5×) and the very long barge versus the long³ barge (4×).
Glider synthesis
The very long barge is the most common 10-cell still life without a known four-glider synthesis. The cheapest known recipe requires five gliders.
