Live Free or Die is a Life-like cellular automaton in which cells survive if they have no neighbors and are born if they have two neighbors. Like Seeds, it naturally explodes at light speed, but spaceships, puffers, and oscillators of infinitely extensible size and period have been discovered, along with rakes and spaceships which move diagonally.
Notable patterns
Oscillators
The rule also allows for the presence of only one still life consisting of a single cell, the dot. Other small oscillators include the checker (duoplet) at p2, the lever, anchor, and radar at p4, the ant at p6, and the monster at p19. The anchor track is an infinitely extensible oscillator that can have any period 4 * (2^n) - 4, which is useful in various flotillas of arbitrarily large periods. Oscillators have also been discovered at p3, p5, and p8. Many oscillators are extensible.
Spaceships
Most spaceships and puffers in Live Free or Die travel at light speed. There is one p1 spaceship with four cells, the moon (known as a photon in Seeds.) Other small, common c spaceships include the free ship (p6), the key ship, plus ship, robot ship, and sun ship (p4), and the octopus ship (p8). Light speed spaceships have also been discovered at p3 and p5. Spaceship flotillas can be built with any period of the form 8 * 2^n or 6 * 2^n.
Spaceships that travel at c/2, 2c/5, c/5, and c/4 diagonal have also been discovered.
Puffers, rakes, and guns
There are a large number of light speed puffers, including many small, common puffers that produce dots or checkers at p4. Other c puffers have been discovered at p3, p5, p6, p7, p8, and p9. Puffer flotillas can be built with any period of the form 8 * 2^n or 6 * 2^n, and complex flotillas can be built to produce oscillators like the monster and radar or to create rakes.
There are known c clean backward moon rakes at a variety of periods and at c/5. Clean sideways moon rakes and sideways or backward free ship rakes can be built using larger flotillas.
There is one known gun, a p4 double-barreled moon gun known as the moon laser.
There are no known non-chaotic breeders.
