Tub with nine (or prodigal[1]) is a 10-cell still life.

This still life is 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 "tub with nine" is usually preferred for this object.

Commonness

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 also the sixty-fifth most common object on Adam P. Goucher's Catagolue.[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 20 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.
