Long shillelagh is 9-cell still life. It is the long version of the shillelagh.


Long shillelagh is the sixty-second most common still life in Achim Flammenkamp's census, less common than the integral with tub but more common than trans-R-bee and R-loaf.[1] It is also the seventy-fourth most common object on Adam P. Goucher's Catagolue.[2]


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.
