Tub with long tail is a 9-cell strict still life. It was found by Robert Wainwright in 1972, and was one of the last 9-bit still lifes to be reported.[1]
This still life is comprised of the normally stable tub with a normally unstable long tail attached.
It can be substitutively referred to as the shillelagh with tub, with the pre-block of the shillelagh replaced with a tub, however "tub with long tail" is usually preferred for this object.
Commonness
- Main article: List of common still lifes
Tub with long tail is the sixty-seventh most common still life in Achim Flammenkamp's census, being less common than beehive at loaf but more common than loaf siamese loaf.[2]
It is the 67th most common still life on Adam P. Goucher's Catagolue, being less common than long integral but more common than cis-bookend and bun. It is the 7th most common still life with 9 cells, being less common than long shillelagh but more common than long canoe.[3]
Glider synthesis
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.
