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.
Information on this still life's commonness with respect to other naturally-occurring patterns is currently unknown.
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.
