Long integral (or S-ten) is a 10-cell still life; it is the long version of the integral sign. Unlike it, it cannot act as a glider eater.


Main article: List of common still lifes

Long integral is the seventieth most common still life in Achim Flammenkamp's census, being less common than hook with tail but more common than eleven loop.[1]

It is the 66th most common still life on Adam P. Goucher's Catagolue, being less common than trans-bun and wing but more common than tub with long tail. It is the 10th most common still life with 10 cells, being less common than boat with long tail but more common than claw with tail.[2]

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.
