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]
An 8G synthesis (click above to open LifeViewer) |
A glider synthesis with 6 gliders is now known.[2]

Occurrence
Among the 240 still lifes with 13 cells, this is the third-rarest of them all according to Catagolue.[3]
