Trans-boat with tail is a 9-cell still life. It was found in 1971.[1]
This still life is comprised of the normally stable boat with a normally unstable tail attached. This is one of two possible isomers, named trans due to the corner part of the boat facing outwards from the tail; the other isomer, cis-boat with tail, has this corner part tucked inwards.
Occurrence
Trans-boat with tail is the twenty-fourth most common still life in Achim Flammenkamp's census, being less common than bi-pond but more common than hat.[2]
It is the 24th most common still life on Adam P. Goucher's Catagolue, being less common than bi-pond but more common than boat tie ship. It is the 2nd most common still life with 9 cells, being less common than integral but more common than hat. Compared to the cis-boat with tail, the trans-boat with tail is about 17 times as common.[3]
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.
