Tub with tail (or twit, originally from the acronym) is an 8-cell still life composed of a tub with a tail that was discovered by Charles Corderman and Hugh Thompson in 1971. It is notable for its use in eater 5.

Commonness

Tub with tail is the twenty-eighth most common still life in Achim Flammenkamp's census, being less common than very long boat but more common than very long ship. It is also the thirty-seventh most common object on Adam P. Goucher's Catagolue.

Glider synthesis

All strict still lifes with a population of 22 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
