Pedestrian Life is a Life-like cellular automaton in which cells survive from one generation to the next if they have 2 or 3 neighbours, and are born if they have 3 or 8 neighbours.
Patterns
Many patterns from regular Life are compatible with this rule. However, traffic lights are much less common, as most predecessors tend to die, giving the rule its name.[1]
There are several natural patterns of interest. One is a statorless, rotating period-106 glider gun:
The second is a family of naturally occurring (5,2)c/190 knightships, using mechanisms meshed together similarly to switch engines:
There are at least 692 variants of these in the simplest form of two engines,[2] and many more such as one which deletes and recreates a blinker, resulting in a period of 380.[3] Many similar technologies result in puffers, rakes and the like.
A third is a (101,3)c/1884 puffer.[4] Due to its massive ash trails no spaceships have been derived from it.
