Long hook with tail is a 9-cell still life. It is the long version of a hook with tail. It is used in an alternate form of the tub-with-tail eater that allows the compression of Herschel loop oscillators to periods of 57, 58, 59, and 60.
It is the 129th most common still life on Adam P. Goucher's Catagolue. Of the ten 9-cell still lifes, it is the second rarest.
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.
