This is one of the 2×2 rules, where any pattern separated in 2×2 on/off segments will continue to evolve as such. And adding a small perturbation in a 2×2 area will quickly devolve into regular chaos. Fairly obvious stuff so far.

However, it seems that within 2×2 areas, there are all sorts of different types of chaos possible. E.g.

1. Complete chaos.

2. "Parallel chaos": Sort of p2. In every other generation, all 2×2 blocks in the pattern will align on every other line.

3. "Domino chaos": Similar to the previous, but all 2×2 blocks, and gaps between them, will be additionally an even number of units long. This ensures that the pattern will have a similar limitation on all phases (though with the "grain" rotated 90° every step).

4. "Weak dot chaos": Sort of p4, alternating between isolated dots/dominos on every 4th line; 4×4 and domino blots; pairs of lines of even length mixed with pairs of dots; and rectangles of width ≥ 6 interspersed with connecting lines.

6. "Strong dot chaos": Also sort of p4, except with the line-pair phase sorted so that every pair of lines is capped by a pair of dots, and that every rectangle phase produces rectangles of width = 6.

Try running a "large preblock" for an example:

Code: Select all

```
x = 4, y = 4, rule = B124/S34
2o$2o$4o$4o!
```

I could document many further types of "chaotic replicator mixtures", but that's not my main point. What I find impressive here is particularly the distinction between "full" and "parallel" chaos — the existence of these as distinct from each other does not seem to be immediately predicted at all.

Also, does anything like this happen in other rules? Do parity restrictions exist in e.g. rules like LongLife (B345/S5)?
