Hook with tail (or snake eater) is an 8-cell still life, consisting of a hook with a tail. It was for a long time the smallest still life without a well-established name; it is now a vital component of the smallest known heavyweight spaceship gun, where it acts as a rock.[citation needed]
Commonness
Hook with tail is the sixty-ninth most common still life in Achim Flammenkamp's census, being less common than loaf siamese loaf but more common than long integral[1] It is also the eightieth most common object on Adam P. Goucher's Catagolue, making it the rarest of the 8-bit still lifes.[2]
Synthesis
On April 29, 2007 Dean Hickerson found a 4-glider synthesis of this still life.[3]
