Re: Can we substantiate this claim?

List of common evolutionary sequences mentions "one of the less familiar fours" (probably the land of lakes) as being more common than the switch engine in census.rle, but does not mention the number of occurrences, ranking, or even which less familiar four it is.
I looked through all census.rle patterns with between 10467 and 687 occurrences, but I was unable to find anything fitting the description.
Does anyone know what it is, or if it exists at all?

I wrote that myself, but I admit the wording is confusing. "one of the less familiar fours, four blocks in a rectangle (1615)" is one entry, not two.

On Wire there's this claim about the zebra stripes wire:
This wire must extend infinitely at the leading edge to avoid destruction, limiting its practical usefulness.
Does this mean it's known impossible to get a signal out of the wire? Is the proof written down somewhere?

EDIT: Since no substantiation was found, I removed the above sentence.

On https://conwaylife.com/wiki/Period-75_R ... o_hasslers, the second oscillator says "found by Carson Cheng on October 2, 2022". At least on the forum I can't find a post from then, and no reference is actually given.

It was posted on Discord. If it was cross-posted, I haven't found who did it or where, yet. It's confusing because Carson Cheng found another p75 R hassler a little over a week later.

There are a lot of hasslers on the wiki which lack proper citations (the reason that the reference to a p10 fleet hassler was removed from the wiki was improper citations). It probably would be a good idea to make it a priority to fill them in on the hassler pages, even if only one at a time.
Currently working to improve Life's guns and work on updating SKOPs and Isotropic rules most similar to B3/S23 to Life standards. Will get software to begin searches eventually.

On OCA:Bosco's Rule page:
..., a range-6 rule containing a quadratic replicator.
What (or who?) it exactly is?

Can anyone verify my claims? (I think they are right but am not quite sure)
I, in Unnamed (34,7)c/156 spaceship wrote: *snip* Until Annelid, in terms of bounding box, unnamed (34,7)c/156 spaceship is also perhaps the largest interesting pattern *snip*
I, in Caterpillar wrote: *snip* it was perhaps the largest interesting spaceship until June 2023, which saw it surpassed by a currently unnamed (34,7)c/156 spaceship by Luka Okanishi of more than double the minimum population, and in 2026 when its further surpassed by Annelid. *snip*
I, in Gemini wrote: *snip* It was the largest spaceship in terms of its diameter and bounding box, having a much smaller population than the Caterpillar. It was beaten by Annelid in both in 2026. *snip*

The Star Trek article heavily lacks information and references. It includes various spaceships in the rule, but that's it. The spaceships all came from the GliderDB database, and only a few of them have discovery information, so I'm guessing the rule is pretty old and some early researchers ran some ship searches. Is it possible to find out who discovered those ships and when?

The article also needs more patterns other than just the spaceships.

EDIT (Aug 6):
Can somebody make a script which can identify a pattern's outer-totalistic rulespace in which it evolves in the same way as in the given rule for a set number of generations? (Preferably Golly-compatible.) I'm trying to track down the sources of the various uncited spaceships in the Star Trek article. I suspect they all came from gliderDB, meaning somebody likely posted it in the Spaceships in Life-like Cellular Automata thread. And since each entry includes the outer-totalistic rulespace of the spaceship (usually), I can use that to try and find the original post containing it.

I sure hope the phpBB forums search engine doesn't troll me or anything! :lol: That sort of thing would NEVER happen.

Since nobody noticed that and my impatience won out over my laziness, I put together this thing:

No luck. :cry:
Any help?
