Elevener (or gull or intentionless) is an 11-bit still life. It is a siamese still life, comprising two eaters 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. It is also the fifty-sixth most common object on Adam P. Goucher's Catagolue.
