Some well known ones:

B358/S23 has this p412 oscillator that's fairly common naturally as far as I can remember (maybe about as rare as the pulsar in Life, not sure if that counts for this thread):

Code: Select all

x = 14, y = 14, rule = B358/S23

EDIT: also this P36 in Day & Night:

Code: Select all

x = 5, y = 5, rule = B3678/S34678

Rare-ish but still fairly common p14 in B3/S12 we all should know:

Code: Select all

x = 7, y = 3, rule = B3/S12

Very small p40 oscillator:

That 3 cell pattern is actually a predecessor of the gun - the lowest population phase of the gun is actually 20 bits (at 2 consecutive generations).

I would say that it is an extraordinary pattern: You have a volatile rule which doesn't hint at all at being explosive (in fact it stabilises quite quickly) with a 3 bit pattern that is a predecessor for a p163 statorless quad gun which fires 2c/13 diagonal gliders, where both the gun period and the ship period are prime and relatively high. That is fantastic! In fact, I'm sure I've run out of superlatives.

In addition, there's a tiny c/2 ship with two interesting head on collisions:

This one synthesizes the gun,

Code: Select all

x = 21, y = 3, rule = B2ce3ai_S2-i3-a5678
2o17b2o$2bo15bo$2o17b2o!
And in this collision one ships eats the other while passing through unscathed.

Code: Select all

x = 14, y = 13, rule = B2ce3ai_S2-i3-a5678
2o$2bo$2o8$2o8b2o$2bo7bo2bo$2o8b2o!
Edit:

Still a bit off-topic, but just wanted to add this push reaction for the gun. One of many I'm sure.

Code: Select all

x = 20, y = 20, rule = B2ce3ai_S2-i3-a5678

Since the above rule is closely related to the extremely oscillator-fertile B2ce3ai/S23 rule, I would not be surprised if it turns out to be omniperiodic as well. Here's a small sample of oscillators (or oscillator predecessors), most of them with extremely similar initial predecessors:

The lack of blocks makes building hive conduits somewhat harder, but I have a feeling that something similar should still be possible.

Even if it isn't, though, the standard (2,1)c/3 signal should still function, correct?

Quite a few B0 rules have naturally-occurring wicks and wickstretchers. I've found that when several of these wickstretchers collide, high-period oscillators tend to form. Here's a bunch of them, in ascending order of periodicity.


In B01346/S0123, the wickstretcher collisions form this p30 oscillator:

Code: Select all

x = 28, y = 28, rule = B01346/S0123

In B013468/S23, they form this p64 oscillator:

You'll notice that I didn't show the wickstretchers colliding to form the p328 oscillator, and that's because it took about 100,000 generations for the whole mess to stabilize and the oscillator to actually appear. You might call it a methuselah if you didn't care much about the size of the bounding box.

Code: Select all

x = 210, y = 210, rule = B013468/S123

In B01346/S123, they form p30 and p2212 oscillators (the p30 is identical to the one in B01346/S0123):

In B013468/S023, they form p82, p242, and p5852 oscillators:

Finally, while B01346/S2 doesn't have naturally-occurring wickstretchers, it does have this very common 6-cell p106 oscillator:

Code: Select all

It's not as common, but there is this 4c/1292 forward rake in B37/S23-i4q5an.

Code: Select all

x = 4, y = 4, rule = B37/S23-i4q5an

Wow. Maybe a pretty smooth rule.

LOL I have actually mostly abandoned the idea of smoothness.

The idea to introduce smoothness is to discriminate complex randomness from absolute randomness (white noise). But after days of search I am continuing improving my algorithm to detect complexity.

And the current idea is to detect covariance between proportion of different neighborhood through time. The idea is that, assume there is cooperative behavior, the number of cells under one neighborhood would co-vary with that in another neighborhood. This algorithim comes out to be the most useful one at the very moment.

This rule is one of its result.

I'm not sure what does it mean. Does it mean counting the cells with B0..B8 and computing the covariance of those numbers?

Yes. When you are counting you have to take account into the current state of the central cell. This would attribute a neighborhood index to each cell. And by monitoring covariance between counts of different index values, we can identify the strength of tangling between neighorhoods.

At the moment I am trying to incorporate mutual information instead of covariance to detect such interaction.
