Its neighborhood is a 4×4 square. Because the side length is even, there is no way for a cell to be exactly in the center. Instead, each cell is affected by cells that are both between two cells above and one cell below it and between two cells to the left of it and one cell to the right of it, and each cell affects cells that are both between one cell above and two cells below it and between one cell to the left of it and two cells to the right of it. This is why spaceships and junk in that rule always move down and to the right.
As it happens, LV supports a general version of that rulespace, since
Build 549. Your neighborhood would be
= hex(111101111011101111000000) = F7BBC0 I think:
Code: Select all
x = 1, y = 1, rule = R2,C2,S,B1,N@f7bbc0
o!
I tried changing it to R2,C2,S46789,B678,N@f7bbc0, but I got the error HROT 'S46789' > 15. How do I fix that?

you have the conditions separated by commas since multidigit conditions are possible with large enough neighborhoods

I also managed to flip the neighborhood so the patterns go in the same direction that I'm used to.

By the way, if one only uses domino sparks, then the pattern turns into a pond, which can be turned back into the original shape with dot sparks (or pairs of dot sparks separated orthogonally by three cells) from perpendicular directions. Is there any way to make that into an oscillator?

I assumed that anyone who is knowledgeable/experienced enough in Conway's Game of Life to stabilize that would also be knowledgeable/experienced enough to know how one could make sure that that reaction was not already known and that Entity Valkyrie 2 would have mentioned if that oscillator were already known.

Yeah, it's known.
Here's the first mention of it I can find — there are a bunch more variants in the thread below the post I linked, but I'm pretty sure the ones EV2 posted (which have been on the wiki at
User:Entity_Valkyrie_2/76P7 since November 2019) are generally the best ones known.

There's a neat way to substitute domino sparks for dot sparks to make the reaction work at period 7:
Code: Select all
x = 55, y = 23, rule = B3/S23
11$37b2o$2bo50bo$2bo33b2o15bo$18b2o15b4o$b2o14bo2bo14b4o13b2o$o2bo4bo

14b4o13b2o$18b2o15b4o$bo34b2o14bo$bo50bo$35b2o!
But sadly there aren't any p7 domino sparkers known that can fit in such close proximity to each other. At all other low periods the spark given off by the reaction interferes with the supporting dot spark. (At period 12 the reaction can support
itself on the top and bottom, using the "pairs of dot sparks separated orthogonally by three cells" approach, but I don't know of any sparkers that would fit on the left and right.) Pentadecathlons fit at p15, but their end sparks are too complicated to substitute for dot sparks. (Karel's p15 doesn't work for multiple reasons.) Above that, I think the only good option would be engineering the sparks into place using guns, which seems overcomplicated just to support a small reaction like this.

Considering that the reaction doesn't need to occur at any specific period, making it work shouldn't be very hard.

Those are all great ideas for stabilizing this, all of which I've tried without success. Sadly, the issue is that there simply don't (yet?) exist less bulky sparkers that can produce the sparks one would need to support the reaction, short of the completely overkill method of synthesizing the sparks with gliders from guns. It might be an interesting exercise to try to stabilize using p120 guns or something similar, but it's not going to be the kind of thing anyone would include in their oscillator collections. I think the best bet to complete it in a way that would be seen as notable would be to find some
slightly better p7 domino sparkers and use the variation I found, but given how much effort people have put in over the years to find p7 sparkers with relatively few good results, I doubt either of us would have much luck without what might be a weeks-long computer search...

Not being able to complete the oscillator is frustrating, but I suppose that a significant proportion of attempts to do something in Conway's Game of Life end that way, and yet we persevere. I suppose that part of the difficulty is that I still haven't developed a sense of what things are worth trying yet.

Don't worry. That kind of sense does slowly develop over time, although it's never perfect. I've been playing with Life for 50 years now, and my sense of what's practical is still not that great!

I'm pretty sure that's a new one. There's a known
5-in-a-row Cordership, but in spite of the relatively large size of this new Cordership, it's actually a 4-in-a-row. It regenerates itself very nicely from its four leading switch engines, so it should be constructible with a dozen gliders plus a few more for cleanup:

Maybe there's a construction order for the switch engines that will reduce the amount of cleanup needed.

That's because it's made from two copies of a yl96 I saw on Catagolue in my symmetry that randomly places two switch engines and a block. Are there any other period-192 Corderships?
EDIT: Wait why are all the corderships on the LifeWiki period-96

Very nice! I don't think population records are being tracked "officially" for p192 Corderships, but this (180 cells in the minimum phase:)

Those are all great ideas for stabilizing this, all of which I've tried without success. Sadly, the issue is that there simply don't (yet?) exist less bulky sparkers that can produce the sparks one would need to support the reaction, short of the completely overkill method of synthesizing the sparks with gliders from guns. It might be an interesting exercise to try to stabilize using p120 guns or something similar, but it's not going to be the kind of thing anyone would include in their oscillator collections. I think the best bet to complete it in a way that would be seen as notable would be to find some
slightly better p7 domino sparkers and use the variation I found, but given how much effort people have put in over the years to find p7 sparkers with relatively few good results, I doubt either of us would have much luck without what might be a weeks-long computer search...
I just found something else:
Code: Select all
x = 6, y = 8, rule = B3/S23

Unfortunately, it fixes the period to ten, which is probably too low for six sparks per period. There might be a way to use a five-period sparker on the long sides, but even if that's the case, any attempt to make an oscillator out of this would be further complicated by the fact that the pattern goes towards the spark, which will make clearance more difficult.
