Excel ↔ Golly
I’ve been seriously thinking about whether it would be possible to build a practical and strategic system for translating between Golly and Excel not just exporting data, but actually translating the underlying Cellular Automaton logic.
Why Excel specifically? Excel is a very ...

Just a small visual reference to the Iranian carpet medallion that inspired the name “ Toranj ”.

That's a wonderful set of images. I can certainly see the connection you're making with the patterns produced from a small ...

Hello, I'd like to request my LifeWiki account (User:MortezaRahmani) to be 'trusted'. Thanks!

Welcome to the LifeWiki! Please read a few posts back in this thread for the usual cautionary notes about where you can document your own work (e.g., your own user page and whatever subpages you create ...

The top-left shift and some other characteristics are correct. However, it does not satisfy all the requirements of the challenge, and it does not produce Toranj in its actual form.
I think you'll have to be more specific about exactly what details you'd like to have match, then.

The cellular ...

4 cells will almost definitely do it.

1 cell will definitely do it. Just start your engineering from the other direction: take any of the bajillion known soups that produce linear growth patterns -- anything you like the looks of from the "yl" column in Catagolue , for example -- and toggle one ...

EDIT: Just discovered the "no creating articles of your own discoveries" rule and will abide. I have posted to the unsure discoveries thread: https://conwaylife.com/forums/viewtopic.php?p=234257#p234257

I've added the trusted flag. A couple of suggestions about "Tännhauser Gate" and other Glyph ...

wln2024, here are several points for you to consider, from me in my capacity as moderator. See also my recent private message to you, when you can access it next week.

1) It is very much against forum rules to use words like "stupid" to label people, or people's opinions. See rule 1a.

2) It is ...

It is stupid to judge any thread interesting or not, someone would move thread to sandbox by personal opinion.
Let them show fairly.
People sometimes put in post reports on new posts, suggesting that they should be moved somewhere else. I think I've moved one of your new threads in response to ...

If you are confirmed the first person who find a unknown eigen letter, my team will stand for your copyright protection.

Hello! It seems like this might be a good time for me to try to explain the serious worries that you generate, every time you mention the idea of "copyright protection".

It's ...

The discussion so far is about parents of an all-ON board -- the T=-1 state. But the title only says "predecessors".

Are the any known results about T=-2 or earlier predecessors of the full board?

... a pattern can move with speed >c/2o temporarily.
Can a pattern move with speed >c/4d temporarily?
Yes, depending on your definitions -- or even >c/4d indefinitely. See Hartmut's linked example above.

However, I'm not sure that that wave is relevant to the original question about gliders ...

- /2/3 -> G3/B2/S
- /2/3H -> NH/G3/B2/S

Generations rule format being unlabeled S/B/G order is a particularly painful detail. Your suggested order and labeling is clearly theoretically superior.

That said -- if a new theoretically-superior rulestring format came into common use, it would mostly ...

A glider facing Northeast is at coordinate (N, N), and the board above the line x = -y is empty except that glider.

My conjecture is that if N is large enough, regardless of the state below x = -y, the glider is never interfered.
Cartesian coordinates, right? The picture doesn't work with ...

Where can I get patterns for the multi-triangle "watercub" stentor variants? There seem to be some images on Discord, but I haven't found any RLE. Maybe still somewhat a work in progress?

How does one use LLS to search for syntheses?
This isn't really an answer, but here are a couple of links that are vaguely related to glider syntheses via LLS:

TigerCub414's first foray into glider synthesis

my brief experiments with LLS , which included at least one round of expanding-ring ...

Another problem that I found on the wiki is that if you're the only person exploring your CA, how are you supposed to document your own discoveries? Storing it locally on your computer works, but then if another person wants to explore your rule, they will need your files to know what's new vs ...

Just make the "hallway" shorter? Is there something I'm missing here?
The length of the incoming "swimmer lane" is arbitrary; shortening it doesn't change the repeat time.

It's kind of funny that we're still stuck with that one obvious but dirty boojum-receiver conversion, having to clean up the ...

As usual on this thread, the "like" from a moderator on Hunter's post means that the trusted flag has already been set.

I am not a spam bot. I like Conway’s Game of Life... Please make me a trustworthy account.

Done. Or rather, you made the account yourself, and I turned it into a trusted account.


I also made a slide gun using Beehive.
Like many introductory notes in this thread recently, the above sentence ...

Isn’t QuFince a catalyst search program? How can it be used to find synthesis components?

QuFince is a generalized CatForce, yes -- the increment idea is even in the name (Spanish "catorce" -> "quince", adding an "F" four places from the end).

However, it's generalized so thoroughly that ...

Try searching for "conway's game of life" on Google -- then wait a little while and watch the right edge of the browser window.

Person notability guideline
A person should only have a page about them created in the wiki if they satisfy at least one of the following criteria...
And even then, it's safer if someone else does the page creation, to dodge the rule about not documenting one's own stuff. Maybe the idea was ...

Hey are you sure about that because I was going to put my own F-heptomino-to-G conduit in the sandbox but they said I wasn't allowed because it is only limited to editors
Pretty sure, yes:

Can I be one?

Please read this post which I think is pretty infomative.
Yes, please read!

There are only three scary things about this latest request for LifeWiki access, but some of them are a little bit hard to fix.

A 61-cell spaceship, technically (see the last few paragraphs) -- but yeah, if we're optimizing for population rather than for complexity or period, RCT15 is currently the way to go.
