Boat tie eater tail is a 12-cell still life.
This still life is comprised of the normally stable boat having been tied to the normally stable eater 1. This is one of two possible ties, in which the boat is attached to the "tail" segment of the eater; the other possible version, boat tie eater head, has the boat attached to the "head" segment of the eater instead.
Commonness
- Main article: List of common still lifes
Boat tie eater tail is the seventy-ninth most common still life in Achim Flammenkamp's census, being less common than trans-boat on dock, but more common than trans-snake on bun.[1] It is also the ninety-fourth most common object on Adam P. Goucher's Catagolue.[2]
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.
