Prodigal[1] (or tub with nine) is a 10-cell still life, comprised of the normally stable tub with a normally unstable nine attached.
It can be substitutively referred to as the integral with tub, with one pre-block of the integral sign replaced with a tub; however, if using a systematic name, "tub with nine" is usually preferred for this object.
Commonness
- Main article: List of common still lifes
Tub with nine is the sixty-first most common still life in Achim Flammenkamp's census, being less common than very long snake but more common than long shillelagh.[2]
It is the 54th most common still life on Adam P. Goucher's Catagolue, being less common than trans-block on long bookend but more common than broken snake. It is the 7th most common still life with 10 cells, being less common than cis-shillelagh but more common than broken snake.[3]
Compared to Catagolue's typical 16 × 16 soups, the prodigal is 25% more common in 8 × 8 soups and 30% more common in 10 × 10 soups, and it is rarer on a torus.
Glider synthesis
All strict still lifes with a population of 21 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.
