Eater head siamese eater tail (or eater siamese eater, or eater with nine) is a 12-cell still life.
Occurrence
- See also: List of common still lifes
Eater head siamese eater tail is the fifty-eighth most common still life in Achim Flammenkamp's census, being less common than cis-boat on dock but more common than cis-block on long bookend.[1]
It is the 57th most common still life on Adam P. Goucher's Catagolue, being less common than trans-bookend and bun but more common than block on cover. It is the 5th most common still life with 12 cells, being less common than trans-block on long bookend but more common than block on cover.[2]
The octo3obj database contains 19 matches for collisions with the still life present in the ash.
Construction
Four gliders suffice to construct this still life.[3] Different known syntheses can be found in Mark Niemiec's database.[4]
