(update synth cost and associated RLE, and remove the claim that there's an official -ly alias for ^7 -- it just doesn't seem like "stupidly long" has ever gotten used much in actual discussions ( https://conwaylife.com/forums/search.php?keywords=stupidly+long )) |
(Per https://conwaylife.com/forums/viewtopic.php?p=181577#p181577 , including both 8G and 6G syntheses, moving one reference to the 6G synth.) |

Long7 snake is a 13-cell still life, an extension of snake.
Construction
For several years this still life has had a known glider synthesis with 8 gliders.[1]
| A 8G synthesis[1] (click above to open LifeViewer) |
A glider synthesis with 6 gliders is now known.[2]
| A 6G synthesis[1] (click above to open LifeViewer) |
Occurrence
Among the 240 still lifes with 13 cells, this is the third-rarest of them all according to Catagolue.[3]
