Commonness
The long boat is the eighth most common still life in Achim Flammenkamp's census, being less common than ship but more common than ship-tie.[2]. It is also the tenth most common object on Adam P. Goucher's Catagolue. It is the second most common 7-bit still life, being less common than the loaf but more common than eater 1.[3]
Synthesis
Long boat can be constructed using only 3 gliders; its first glider synthesis was found by John Abbott.[4]
gollark: Not yet.
gollark: On what?
gollark: GTech™ personality test.
gollark: Oh, I should ask about favourite fundamental particles too.
gollark: By symmetry, it should have "still", I suppose.
