No 15G SMOS or OMOS has been made yet, so a remake seems premature. Certainly we'd start with the hyper-optimized RCT15, and just replace the relatively few recipes that would need to change.

With the right reaction(s) attached, could a single-engine cordership be theoretically possible?

Because we can build diagonal c/12 macro-spaceships and puffers and rakes, there are lots of things (like this idea from 2020 , or the "swarm of Caterloopillars" from 2017) that we could attach to a ...

It's a common request in the Construction Challenges and Ideas thread. Most recently addressed here, I think, though it may have come up again once or twice.

Where can I find their syntheses?

See the link in the first post of the 23-bit still life syntheses project thread.

Hello! I'm showing up and doing some moderator shenanigans because a couple of posts above got reported.

@smolobserverxd, I'd like to echo all of what others have said so far, using my Official Moderator Voice:


Welcome to the forums! (make sure to review the forum rules )!
You can put patterns ...

Fractals produced by systems of affine transformations are indeed very awesome. John Hutchinson and Michael Barnsley called them "IFS fractals" back in the 1980s, IFS standing for "iterated function system". Not sure if that's still a commonly recognized term, but "chaos game" seems to have survived ...

obviously a lot of label work went into this ...
Just to reiterate -- as long as the source data is kept up to date, there's no need to painfully rework all of the popup LifeViewer labels whenever one oscillator's bounding box is changed. Just re-run the script and regenerate the labels.

I'm ...

Also a lot of those oscillators' stators need to be update[d]...

I am sure there are more relevant examples where such stator improvements are necessary, but I was particularly disappointed to see these chucklebait monstrosities again
The RLE that will need to be updated is the text of the ...

While I’m here, the oscillator stamp collection present in Golly is outdated — it lacks periods 19 and 41...
Yes. hotdogPi put together a newer version ( oscillators.rle ), but it didn't make it into Golly 5.0.

We're also thinking about continuing to adjust Golly's base pattern collection to ...

Update for everyone interested in working on Golly's pattern collection:


I've implemented a geturl command for Lua scripts ...
The Lua geturl command has now found its way into an official Golly beta build . So now would be a great time for someone to put on the Golly Pattern Collector's Hat ...

It's great to have this both online and downloadable -- many thanks!

Are you planning to add any more aperiodic tiling families? There's one example in the list that's labeled "Spectre variant", but the tiling still looks like a hat tiling and I can see two orientations of tiles. It would be fun to ...

Is the " exponentially spaced binary counter " (last nomination with no description in the nominee table ) really an exponentially spaced binary counter? Its height grows linearly, and there's a changing pattern of slow spaceships, fast spaceships, and still lifes between the spaceship source and ...

can anyone please convert this python script to lua...
In the spirit of "teaching people to fish", I'm going to avoid spending the necessary three minutes on this myself.

In my experience, ChatGPT or other LLMs like Claude Code have been perfectly capable of doing this kind of port for you, for ...

Hello. I'm a long-time lurker, but would like to request that my account, Nosferattus, be granted Trusted status.
Done, and welcome to not-lurking!

The usual advice applies: rather than jumping straight into adding articles to the LifeWiki, start by posting the things you're going to want on the ...

462 is correct, wow!

(You don't need math, you just have to copy the input and paste it back in again at T=462, and confirm that the beehive gets there just in time to meet it.)

58P5H1V1 to two gliders...
Repeat time 1070, looks like. And there's another glider available:

x = 306, y = 341, rule = LifeHistory

$257.3A$259.A9$286.A ...

I was musing whether there could exist patterns that have “few” predecessors (but not are not really self-forcing), and could still give rise to non-glider-constructible still-lifes. Very speculative.
Yup, it seems possible that a still life can be found that doesn't contain any self-forcing ...

Thanks -- forwarded this to the most recent email address that I have for Dean Hickerson.

I don't think you should beat yourself up about messing up, I think this is just a sign that we should put more time and effort as a community into curating and creating the nomination text and list.
Amen to all of that! Organizing one of these POTY/DOTY votes is just incredibly difficult and ...

Hmm, another month is disappearing fast. Any more nominations? Anyone care to volunteer to build out the full list of nominations for 2025 Patterns and Proofs, and post it here? It's a painstaking and time-consuming task, but it won't be a thankless task because I will definitely thank whoever does ...

I reported all the double posts and triple posts.
Thanks for acknowledging the multi-posting problem!

Now there's just one more minor detail to straighten out a little bit. Double/triple posts aren't really something that you're supposed to use the post-reporting system for.

In this case you ...

I guess I should start with pointing out that all definitions are just made up words...
Absolutely. You've come across an alternate way of partitioning large still lifes into smaller still lifes, different from the one that's mandated by "strict still life" / "pseudo still life" / "quasi still ...

Is it possible for pseudo still life components to be connected orthogonaly?

It seems that all definitions of strict still life assume by default that islands (polyplets) are indivisible - is there a proof for that?


It is possible.

x = 10, y = 10, rule = LifeHistory
4.A$2.3A$.A$.A.2A2C ...

Why rename the orientations? Aren't they fine as is? (I'm not trying to shut you down, I just want to hear your reasoning.)

Consider this H-to-S, it is definitely not F, but it is also not Bx.
I see the problem, but I don't see the solution. The lookup table you've given only maps F through ...

We certainly need enough newcomers to replace the steady erosion of community members who drift away for various reasons. So we do have discussions now and again about how best to expand the community .

More newcomers isn't always automatically better, of course. If we used our current standard ...
