Long snake (or python) is the first extension of the snake still life. It was found by John Conway no later than 1970 as part of an early still life enumeration,[1] although does not appear to have been published until 1971.[2]
Occurrence
- See also: List of common still lifes, Most common objects on Catagolue
Long snake is the forty-third most common still life in Achim Flammenkamp's census, being less common than cis-boat with tail but more common than trans-mirrored bun.[3] This makes it the rarest of the four 7-bit still lifes in this census, over 200 times rarer than the second rarest, eater 1.
It is the 42nd most common still life on Adam P. Goucher's Catagolue, being less common than loop but more common than fourteener. It is the rarest still life with 7 cells, being 177 times rarer than eater 1.[4]
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.
