Long3 snake (or extra long snake, or very very long snake) is a 9-cell still life. It is the long3 extension of snake. It was found in 1971.[1]
Occurrence
It is the rarest 9-bit still life, appearing less than half as commonly as long hook with tail.
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.
