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: > harvard isn't a german universittyYET.
gollark: You could probably just go to whatever university is reasonably good and cheap near you and say "studied economics" and nobody would care much.
gollark: Again, probably not several hundred kilo$ in benefit there.
gollark: I mean, yes, but possibly not several hundred kilodollars handy.
gollark: There are likely HEAVY diminishing returns.
