RGB332 feels similar to what I described above. You would still want to increment 75 at a time to avoid similar colors next to each other, though.

Depending on what unname4798 wants to use the RGB332 rule for, it might be better to have the states organized in some easy-to-predict enumeration with similar colors next to each other.

At the moment Display256 doesn't seem too likely to get changed to anything else, so we already have a solution for "similar colors not next to each other" -- we're more talking about a new and different rule table for some other purpose. That purpose still hasn't been stated, I think.

Should Template:StillLifeComponent have a 'family' parameter? (I have already asked this on the tiki bar.)

What would be the intended use? What would be allowed values, and consequences of specifying a value? It's not obvious. Would be easier to understand the idea, if details of that kind were written explicitly.

It would be use for extended versions of a induction coil. For example a dock would be in the house family.

[confocaloid]

I'm not sure that's well-defined enough to go into infobox. I think it would be better to put that kind of information into article text, outside the infobox.
For example it's not clear why a dock should be in the house family. What else would be in the same family? What would be other families? Is there an intuitive underlying system that answers most such questions by a few simple rules? Or it's going to become arbitrary choices and points of contention between different wiki editors in future?
Additionally, each new parameter in the infobox increases height of the infobox. It's best to keep infoboxes compact, and put most content in text.

In the 'LifeWiki:Game of Life Status page', section 'c/4 diagonal spaceships, puffers, rakes':

The summary should be changed from 'All periods over 3488 are known' to 'All periods over 2752 are known',
since my post from 10 April improved the bounds.

I will give a timeline of the events of the p49 bouncer loop page

• 1999-08-01: Noam Elkies finds 440-cell pipsquirter-based glider reflector loop
• 2003-01-24: Karel Suhajda finds a new pipsquirter, which reduces it to 400 cells
• 2009-09-14: In Talk:400P49, Matthias Merzenich decides that the pages 440P49.1 and 400P9 ought to be combined into "p49 glider shuttle," which later became p49 bouncer loop. He also proposes that the newer version be used in the infobox
• 2019-11-20: Dongook Lee finds another new pipsquirter, which reduces it further to 380
• 2022-12-21: I note it in Talk:p49 bouncer loop
• 2023-10-23: Galoomba adds the new minimal version to the page (initially 384, then a stator reduction later that day)
• 2024-04-19: In making the table now in Relay, I realise it supports all periods 35 + 14*n (the p35 representative also being fourfold rotationally symmetric)
• 2024-04-21: Ever the indecisive contrarian who doubles back on himself over 14.6 year intervals (), Matthias Merzenich replaces the 400-cell version in the infobox with the 440-cell one

Which representative should be used; the original, the one found 3.5 years later, or the one found 20.3 years later?
Here are some parallel prior instances:

• 180P8: Infobox version was reduced from the original 392P8 over the course of 2.8 years
• 258P3: Was reduced to 246 cells after 5.6 years, and to 244 after 21.7 by a stator reduction by Entity Valkyrie; neither is included
• 754P7: Was reduced from 1308 to 754 cells after 0.1 years (which is used), and to 678 after 0.84 (which is not)

As you can see, the acceptance of reductions to infoboxes/titles seems to be an inconsistent phenomenon. We shall discuss whether the first or smallest version of an oscillator is most useful to include (myself, I tend to agree with Matthias Merzenich's past self), until maybe a moderator can settle it to declare as a general rule or guideline.

Edit: For what it's worth, if we admit ourselves 5 gliders instead of 4, it could also be called the p28 bouncer loop, and it admits constructions of oscillators of all periods 28+7*n.

[confocaloid]

(1) If there is an infobox, then the infobox should at least be self-consistent. If it shows some specific pattern then it should describe that specific pattern.

(2) For article topics "the first known pattern of this type" (for example if the article is about the first known oscillator of a specific period), the infobox should show the original version, whenever that's possible.
If the original version is too large to be put in the infobox, nothing prevents hiding the infobox pattern (hideimg = true), and putting all patterns in the main part of the article instead.

Edit: For what it's worth, if we admit ourselves 5 gliders instead of 4, it could also be called the p28 bouncer loop, and it admits constructions of oscillators of all periods 28+7*n.

As already noted on the talk page ( https://conwaylife.com/w/index.php?diff ... did=148364 ) the article p49 bouncer loop is about the first known p49 oscillator, and shouldn't be moved to any other period.

In my defense, at the time the newer version was also the smallest p49 oscillator. I was trying to choose what I thought at the time was the most notable form. It was a judgement call that people could reasonably disagree with. When snark loops were discovered, the bouncer loop was no longer the smallest p49, so the original form became unambiguously the most notable form. I meant to change it eventually, but it was always a low priority. I was suddenly inspired to complete this task when I saw some posts on the talk page. The p26 pre-pulsar shuttle page should likewise be changed to use the original form, with the smaller variants included in the gallery.

And I know you're just being cheeky, but the "indecisive contrarian" comment could potentially be interpreted as negative by some. I know I sound like the "no fun" guy, but please try to avoid descriptions of other users that could even potentially be viewed negatively.

Which representative should be used; the original, the one found 3.5 years later, or the one found 20.3 years later?

In this case, the original should be used, as it's the first known p49 oscillator. None of the other variants have a similarly notable property. Being the former smallest isn't as notable as being the first.

Generally, I think the most notable variant of a pattern should be used in the infobox. What property makes a pattern most notable can change over time, even reverting back to an earlier form.

Here are some parallel prior instances:

• 180P8: Infobox version was reduced from the original 392P8 over the course of 2.8 years
• ...
• 754P7: Was reduced from 1308 to 754 cells after 0.1 years (which is used), and to 678 after 0.84 (which is not)

These are notable for simply being strong sparkers of relatively high period. In these cases I would say the "nicest" version is the most notable. That would generally be the smallest as long as it doesn't significantly sacrifice clearance around the spark.

258P3: Was reduced to 246 cells after 5.6 years, and to 244 after 21.7 by a stator reduction by Entity Valkyrie; neither is included

This one could probably be moved to a p3 domino sparker page that lists several variants without using an infobox.

if we admit ourselves 5 gliders instead of 4, it could also be called the p28 bouncer loop, and it admits constructions of oscillators of all periods 28+7*n.

The p28 bouncer loop is not notable enough to have its own page. It could be included on the p7 bouncer page if someone feels so inclined to add it. An argument could be made that the p49 bouncer loop could also be merged into the p7 bouncer page, but I personally wouldn't bother.

[DroneBetter]

In my remarks upon User talk:H. H. P. M. P. Cole/ConwayLife 2050, I formalised one of their conjectures,

Is there a pair of constants c₀,c₁, such that for any synthesisable still life, there exists a sequence of constellations (with the last being the still life itself), such that a set of ≤ c₀ gliders may be added around the nth member to produce the n+1th, whose effect in each stage is constrained to a c₁ × c₁ bounding box?

Would this be considered a meaningful problem to be solved, and does it warrant inclusion in the Problem page? And does anyone have heuristic evidence of its falsehood, ie. a wick for which the only known synthesis methods are to construct all segments simultaneously?

[confocaloid]

No strong opinion on the specific problem you asked about,

[...] and does it warrant inclusion in the Problem page? [...]

however, I believe it would be an improvement if the wiki entry Problem would be shortened, and would list fewer specific problems/conjectures and instead give more "Further reading" hyperlinks at the end.
Otherwise, there are just way too many specific interesting conjectures and problems to list them all.

[unname4798]

Administrators, could you remove my common.js? I have played too much with substitution.

[hotdogPi]

Done.

[b-engine]

The LW:NB is still confusing that I couldn't even know if a pattern is notable.

Is a smoking spaceship even notable? There're only a few smoking spaceships in the category.

Can

[confocaloid]

The LW:NB is still confusing that I couldn't even know if a pattern is notable.

I think the important part is this:

A topic for which this criterion is deemed to have been met by consensus is usually worthy of notice. Verifiable facts and content that are not deemed notable may be appropriate for inclusion in a separate article.

To prevent overenthusiastic edits and conflicts of interest, a commonly accepted rule is that the discoverer of a pattern, inventor of new terminology, writer of a program, etc., etc., should not be the one to document that pattern, term, or program on the LifeWiki.

If you create a dedicated article about something discovered by someone else,
and if several months (or even years) pass after the page is created,
and if nobody objects to the existence of the page and there are no controversies about it

...that probably means that the topic of the article was indeed [considered] notable at the time.
