Long canoe (or long sinking ship) is a 9-cell still life, the first extension of canoe. It was found in 1971.[1]


Main article: List of common still lifes

Long canoe is the seventy-seventh most common still life in Achim Flammenkamp's census, being less common than trans-rotated bun, but more common than trans-boat on dock.[2]

It is the 71st most common still life on Adam P. Goucher's Catagolue, being less common than loaf siamese loaf but more common than eleven loop. It is the 8th most common still life with 9 cells, being less common than tub with long tail but more than 4 times as common as long hook with tail.[3]

Glider synthesis

All strict still lifes with a population of 21 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
