Herschel or r? If by "common" you mean forms the most not necessarily from a three glider collision

I meant that forms from the most three-glider collisions.

idk but herschel forms from a lot of them (make a b for 2g, then delete the block)

Yes, but should slightly different timings count?

Nah.

[MathAndCode]

Nah.

So then what object that has no two-glider synthesis is formed by the most three-glider collisions where the third glider would not have led to the same result in the same way by arriving one or two generations earlier?

Almost certainly the R, or if you wanted to be annoying the pre-block (all 2G collisions which produce it have dying sparks at that stage) or the 4 cell Z-tetromino beehive predecessor (the 2G also produces a spark at that stage)

[ENORMOUS_NAME]

are there any asymmetric objects that appear more common in some symmetry

[goldenratio]

xp4_37bkiczy1359a4 is one of them
Achim's p8 (xp8_25du4szx327ba4) is also much more common in D2_x, though there's slightly more soups in C1 and many more soups in G1 as they have been searched a lot more.

[MathAndCode]

Almost certainly the R

That was my best guess, but other common sequences, like wing and century, would also be plausible.

Are there any metacells or any other method of emulating Margolus rules in CGoL?

0E0Ps or OTCAs running 2x2.

Ok, well I know that. I even just accidentally made a B1 rule that can emulate a Margolus rule (B12347/S123458). Let me rephrase my question then: Are there any metacells or any other method of emulating any arbitrary Margolus rules in CGoL?

I think the 0E0Ps can simulate arbitrary Margolus rules.

What is the smallest-period oscillator for which every cell in the rotor changes state at least four times per period? Six times? What about the highest-period oscillator for which every cell in the rotor changes state exactly two times per period?

For any N, there's a p43N+1 oscillator where every cell in the rotor changes state at least 2N times per period — but for specific values of N I'm not sure about improvements to that upper bound...

It doesn't say anything on the LifeWiki page like that.

Is there an existing catalogue of eater welds? Or should I make one?

[ColorfulGalaxy]

What do you mean by "eater welds"?
Does that include oscillators like "eater plug"?

No. Sometimes we need eaters close to each other in conduits, so new still lives with two eater heads are needed.

It does include oscillators, but ones like test tube baby, with two heads.

Would this dot sparker count as medium or strong?

Code: Select all

x = 8, y = 5, rule = Symbiosis
B5.AB$.A$.B3A$3.A$5.BA!

Medium, as the sparker is still changed (advanced by one generation) if the spark is removed even if it technically isn't destroyed.

Ah; thank you for explaining.

How can I search custom rules in apgsearch?

How can I search custom rules in apgsearch?

./apgluxe --rule (Your rule)

Then run ./apgluxe again

Q: What does those 1 2 3 and A B C D mean in jslife sparker tabulations?
