Elevener (or gull[1] or intentionless[2]) is an 11-cell still life. It consists of two siamesed eater 1s that share three cells of their tails while retaining both their glider-eating and boat-bit-catching capabilities.


Elevener is the forty-seventh most common still life in Achim Flammenkamp's census (the second-most common of its size, after the boat-ship-tie), being less common than bookends but more common than block on cap.[3] It is also the fifty-sixth most common object on Adam P. Goucher's Catagolue.[4]
