DrighLife is a Life-like cellular automaton with the rulestring B367/S23, in which cells survive from one generation to the next if they have 2 or 3 neighbours, and are born if they have 3, 6, or 7 neighbours. The name is a combination of DryLife (B37/S23) and HighLife (B36/S23).
This rule is explosive as small patterns like pi-heptomino may exhibit chaotic growth. However, the smallest solid 1 × N pattern that exhibits infinite growth is 1 × 33.
Patterns
Still lifes
The list of still lifes in DrighLife is identical to the list in HighLife, as B7 requires at least one of the adjacent cells to have four or more neighbours, making still lifes with the possibility of B7 impossible.
The long boat is much more common, as the V-pentomino and W-pentomino evolve into a long boat. Loaves can still form in other ways.
Oscillators
The p7 and p10 from HighLife work in this rule.
| Four high-period oscillators found by FWKnightship. From left to right: p46, p58, p60, p138[1] (click above to open LifeViewer) |
Spaceships
| The most common orthogonal spaceship by far, more common than Life's XWSSes (which don't work in DrighLife), but not as common as the glider. It's 2c/8, glide symmetric. (click above to open LifeViewer) Catagolue: here |
| These 3c/8 mechanisms (failed puffer on the left, complete spaceship on the right) were found by May13 (click above to open LifeViewer) |
| 3c/8 p24 and p48 spaceships also found by May13 (click above to open LifeViewer) |
| A 2c/5 orthogonal spaceship (click above to open LifeViewer) Catagolue: here |
