Blinkers is a Life-like cellular automaton with rulestring B345/S2. Evolution in Blinkers usually stabilizes after a few hundred generations, leaving almost exclusively blinkers (hence the rule name) and rarely some larger oscillators.
No finite still lives can exist in Blinkers: if a pattern contains cells that have 2 live neighbours each (like a pre-block, tub or beehive), it must always trigger at least one of B3, B4 or B5 conditions.
Oscillators
A blinker is the most common object in this rule, about 7.5 times more common than the oscillator from the 2nd place. Some other oscillators known from Life, like the toad or clock, work in Blinkers as well. 10 most common oscillators in asymmetric soups, according to Catagolue, are shown below.
Oscillators with several different periods are known, the highest being p112. Odd periods are much more rare than even periods: only two examples of p3, one of p7, and one of p19 are known. Smaller p3 was found by LaundryPizza03[1].
