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.

Occurrence

See also: List of common still lifes, Most common objects on Catagolue

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

Main article: 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.
