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.
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 also the seventy-seventh most common object on Adam P. Goucher's Catagolue.[2]
All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
