Ship tie snake is a 12-cell still life. As its name implies, it involves a ship having been tied to a snake.
Construction
| A 5G synthesis[1] (click above to open LifeViewer) |
A 5-glider synthesis for this still life is shown above. A number of known alternate syntheses can be found in Mark Niemiec's database.[2]
Occurrence
Ship tie snake is the 144th most common still life on Adam P. Goucher's Catagolue, being less common than krake but more common than beehive with hooked nine. Among all still lifes with 12 cells, it is the 17th most common, being less common than claw at claw but more common than twelve loop.[3] There are no occurrences of this still life in final patterns of collisions in the octohash, octo3obj or octo3g databases.
