Tub with tail (or twit, originally from the acronym) is an 8-cell still life discovered by Charles Corderman and Hugh Thompson in 1971.[1][2] It is notable for its use in eater 5.
This still life is comprised of the normally stable tub with a normally unstable tail attached.
Commonness
- Main article: List of common still lifes
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.[3]
It is the 29th most common still life on Adam P. Goucher's Catagolue, being less common than very long boat but more common than mirrored table. It is the 6th most common still life with 8 cells, being less common than shillelagh but more common than canoe.[4]
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.
