Request for original records for "light speed oscillator"s, now merged in a new article, that were discovered by Josh Ball in August 2007. Game of Life News mentioned a period-6 version but not the period-5 variants.
There really isn't much -- a message forwarded to the old LifeCA email list by Heinrich Koenig...
Thanks, I think that is sufficient for the page. They are among the many articles that Scot Ellison (Scotgot) had created a decade ago without providing a reference, and so may puzzle readers a bit about where the user had seen the patterns. Here is a list of other pages with the same issue: The last two has been questioned for notability as well. So I suppose citations for pattern source will be useful for the sake of life history.

I just corrected the criteria for the D8_2 property (symmetry between odd and even bilateral symmetry) via rigorous evaluation, and the relevant content in the article Static symmetry will need to be corrected.

The following are red links on the "Table of oscillators by period" page:

p189: 32P21 on 56P27
p190: Fumarole on 44P38
p192: 31P3 on Merzenich's p64
p216: figure eight on 56P27
p266: 34P14 shuttle on 44P38
p280: figure eight on p35 honey farm hassler
p297: p11 domino sparker on 56P27
p342: p18 bi-block hassler on 44P38

Can anyone point me to rles or apgcodes for these named patterns?

Thanks.

These all look like ones that I found. They're descriptive enough that you can probably easily figure out what they are by putting the two components together.

31P3 has probably been obsoleted by 30P3.

I would probably prefer some to still be dead end links, a lot of pages you made (like a page for me) doesn’t quite meet the notability guide lines

This is not about notability. It is poor practice to intentionally provide users with dead-end links, especially when the point of this page is to provide links to the SKOPs. I have made a number of the links on the page that were red go to Catagolue. Others have been directed to an appropriate section of an existing page where a pattern is included (e.g. a gallery entry). If I had rles or apgcodes, I could change the noted dead-end links to Catagolue links.

Should I put something on the wiki page for Traffic stop mentioning its use to create the smallest period-36 glider gun? Maybe:
It has been used to create the smallest form of the p76 pi-heptomino hassler, the smallest period-46 glider gun, the smallest period-36 glider gun and, most notably, the first period-38 oscillator.

1)The beehive stopper article mentions an H-to-beehive factory with the same function. Can this earlier one also be included?
2)Can this glider-to-boat converter be added to glider to block article, as this modification has turned out to be useful for record-breaking HWSS-to-G converters and faster 2c/3 signal receivers?

Those seem more or less reasonable to me. I don't offhand know of a case where that old H-to-beehive is an improvement on a beehive stopper or a glider stopper, but there's a lot more flexibility in the input lanes, so it might come in handy somewhere:

At the moment @Apple Bottom is creating a bunch of pages for 16-glider RCT terminology, citing a fresh article by @dvgrn. Why not simply put all of these details into the corresponding section of the main reverse caber tosser article? Do they have something to do with other circumstances where individual definitions are significant, such as an upcoming update of Life Lexicon?

EDIT 1.5 hours later: @Citation needed (or @CurrentNews), you don't have to drop the proposed move tags so quickly.

I don't think it's quite notable enough. 57 and 126 never got pages. While 117 did, it's frequently used in multiples unlike the others.

(What is it with them all being multiples of 3?)

The article for Superstring on the wiki says, "In August 1998, Stephen Silver proved that odd-period superstrings are impossible." What is this proof?

The article for Superstring on the wiki says, "In August 1998, Stephen Silver proved that odd-period superstrings are impossible." What is this proof?
I don't think it's been posted publicly. Here are the contents of an email from Stephen Silver containing the proof (code tags added for clarity):
On August 9, 1998, Stephen Silver wrote:Dieter Leithner recently sent me all the superstring postings, which
predate my joining this list. As Nathan Thompson pointed out at the
time, all of Peter Rott's superstrings have even period. It turns out
that there is a very good reason for this: odd-period superstrings are
not possible in Life.

The proof is not very difficult. The first thing to note is that the
second row of a superstring behaves like the 1-D cellular automaton
with rule B01S0. This is a self-dual rule. To get an odd-period
superstring we need an odd-period agar in this 1-D rule. There is
one very obvious such agar, an alternating sequence of ON and OFF cells,
which is p1. This agar, however, can never give an odd-period superstring.
To see this it is necessary to examine the third row of the superstring.
For half the cells the picture looks like this (the superstring is moving
up the page):

Code: Select all

OOO
O.O
???
It is clear that whatever the ?s represent, the middle cell of the
third row will be OFF in the following generation, and similarly in all
future generations. Since the superstring is assumed to be periodic this
cell must already be OFF. For the other cells in the third row the picture
now looks like this:

Code: Select all

OOO
.O.
.?.
If ? is ON, then the middle cell of the third row will be OFF in the
following generation. But if ? is OFF, then it will be ON. So the third
row is p2.

So if we could prove that the 1-D rule has no odd-period agar other than the
one discussed above then we could immediately conclude that there are no
odd-period superstrings. In fact something stronger holds:

Claim: With the exception of the trivial p1 agar, all agars in the 1-D rule
are p2 and statorless.

To prove this, consider the four-cell sequence 0010. You can easily check
that this can only arise from the sequence 110101. And the middle part of
this sequence, 1010, can only arise from 010101. So the pattern 0010 can
only arise in a position which has previously always been 1010, it can never
be part of an agar (which is, by definition, periodic). By duality and
symmetry the same applies to 0100, 1101 and 1011. But this means that the
only agar that contains the sequence 010 (or 101) is the p1 agar discussed
above. The only three-cell sequences that can occur in other agars are 000,
001, 011, 100, 110 and 111, and in all these cases the middle cell changes
state. The agar is therefore p2 and statorless, as claimed.

---

Note that the above proof shows that (periodic) superstrings fall naturally
into two classes, those with a p1 second row and those with a p2 second row.
I will call these Class 1 and Class 2, respectively (not to be confused with
Peter Rott's Type 1 and Type 2). The examples that Peter Rott posted in
August 1996 are almost all Class 2.

This division into Class 1 and Class 2 works not only for Life, but for
any rule in the range B3S23 to B12345678S0123678 (although some of these
rules may not admit periodic superstrings at all). However, my proof that
Class 1 superstrings have a p2 third row doesn't work if births can occur
with 5, 6, 7 or 8 neighbours, such as in HighLife. (In fact it is possible
in HighLife for a Class 1 superstring to have a p1 third row, but I haven't
made any serious attempt to determine if such a superstring can have an
overall odd period.)
Edit: while I'm on the subject, here is Peter Rott's boat-based superstring support:

Code: Select all

x = 109, y = 25, rule = B3/S23

Very likely. What specifically are you interested in? I'm guessing you're looking for a tutorial for what to do when you have a spaceship synthesis, but no completed gun for that spaceship?

There are two main ways to build spaceship guns. One is to pick a workable period with an unusually small edge-shooting gun, and build the spaceship gun at that period, with N copies of the gun (or more or less) for an N-glider spaceship recipe.

However, period-specific guns don't get built very often any more, because then you have to do the work all over again if you ever want a different-period gun for that spaceship. So the second way to build a spaceship gun is to build a glider-to-spaceship converter, and then attach a gun to it.

If you're looking for a tutorial for G-to-spaceship building, can you give some description of where you currently get stuck? What do you want to know that can't be found in Chapter 7 (especially Section 7.5) and Chapter 8 of the Life textbook, plus various walkthroughs here on the forums like this one? There are a lot of different toolkits that can help build this kind of thing, so if you want to know about one toolkit in particular, that would be good to know.

I'm mostly interested in building guns of a specific period for a spaceship with a glider synthesis but not a gun like 31P8H4V0 (admittingly, my goal is to build a Canada Grey gun). All those timing issues and connecting Herschel conduits in G-X converters seem way beyond my ability.

Got it. Okay, for something like 31P8H4V0 the method will be somewhat along the lines of what we did here -- if you read the next several posts and inspect each stage, you'll notice in particular that Goldtiger997 has a script that can place guns automatically, though not entirely reliably.

For a Canada Greyship gun I'd suggest that some kind of assembly script is going to be the only way to go. Even there I personally think that a glider-to-greyship converter would be much more entertaining than a plain gun -- but I'm known to have silly biases in this area.

So ... no promises on an immediate tutorial or walkthrough, but the more specifics you can post about what exactly you're having trouble with, the more likely it is that something like that will appear. Maybe start building a 31P8H4V0 gun in the Construction practice thread, and ask any questions there.
