This is Baker's Dozen. This was traditionally hassled by caterers or jams or other oscillators, but eater2s will likely be cheaper and more compact. I am not sure if this stabilization was known before.

This method has indeed been discovered before; I forget by whom.

Wow! Congrats! How did you find this? I am not even sure if one can tweak WLS settings to find this kind of thing!

Nicolay Beluchenko's version of WLS does allow you to search for exactly this kind of thing. There is an option to limit the number of cells in the stator, even down to zero.

This is just stillater with a much larger stator. If you want to know whether an oscillator was previously discovered, you should first check jslife under the 'osc' folder (jslife is available here).

Wiki page then?

muzik wrote:Wiki page then?
I'd say no -- not quite that neat a find. P4 is a low enough period that if this oscillator counts as wiki-worthy, people could crank up WLS or JLS or whatever and generate hundreds more period-4 objects, and it would be hard to say why they were any less wiki-worthy than this one. The same goes for the piles of unnamed period-4 objects already collected in jslife.

Notice that the Oscillators of period 4 group in the LifeWiki currently has only 35 objects, almost all of which were (a) discovered in the early 1970s, (b) have useful sparks and therefore get included in all kinds of circuitry, or (c) both.

Of course, my flowchart for answering the "Wiki page?" question is pretty simple:

Wiki page? --> No

-- or, more seriously,

Multiple people have been talking about object fairly regularly for multiple years?
Yes --> should have a wiki page
No --> shouldn't have a wiki page yet

Of course you can perfectly well reduce "years" to "months" or "weeks", in special circumstances... but really, in most cases, there's no need to be in a big hurry to decide. If this new P4 turns out to provide a spark for a new smallest color-changing p4 glider reflector, or something along those lines, then it will end up on the wiki with no need to ask the question.

There aren't many p7s... I'm assuming any new p7 rotors would deserve a page then.

Speaking of p7s, I haven't been having way too much luck searching for the T-nosed p7... anyone else up for the challenge?

I would say "no". First, there are a lot of known p7s (see o0007-bil.lif). Second, even if there weren't, that doesn't automatically mean any new oscillator should get a page. For example, there are only a few p13 oscillators, but most of them are boring billiard tables. In my opinion, the only known p13s that deserve a page are Buckingham's p13 (the first) and Nicolay's p13 (the smallest).

There are currently many patterns that should have pattern pages but don't (for example, the 9 oscillators listed here). Focus on these pages first.

As a last note, here is an important question to ask yourself before adding a new page: "What other pages should link to this page?" (not counting category pages). If there isn't a good reason to link to your new page, then it's probably not notable enough to be included on the wiki.
