|Pattern type||Strict still life|
|Number of cells||9|
|Discovered by||Robert Wainwright|
|Year of discovery||1972|
Two copies of this still life can position themselves in such a way so that they share two-fold C2_4 rotational symmetry. In this orientation, they can be considered one strict still life and fit in a 6×6 bounding box, giving the resultant still life the highest density of all still lifes fitting inside such a bounding box.
Long shillelagh is the sixty-second most common still life in Achim Flammenkamp's census, less common than the tub with nine but more common than trans-bun and wing. It is also the seventy-fourth most common object on Adam P. Goucher's Catagolue.
All strict still lifes with a population of 20 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
