c/3, I think, or rather 5c/15. So the answer is ... maybe?

It could become a tagalong, if a 5c/15 spaceship is ever found that provides the right dying sparks in the back -- there are lots of options that would support that as a back end:

Code: Select all

x = 9, y = 5, rule = B3/S23

#C [[ GPS 5 TRACK 1/3 0 ]]
[[ PASTET EVERY 15 PASTEDELTA 5 0 PASTE  6b3o$5b4o$2bo2b3o$2ob2o$2bo3bo! ]]

Offhand I'm not seeing how it would be likely to be a spaceship engine on its own though.

We're a long way from being able to hunt effectively for 5c/15 spaceships with our current search tools. The period is way too high. And the support doesn't look like it would work with a lower-period spark.

Unfortunately, my width 20 (logical width 10) symmetric c/8 qfind v2.2 search finished without finding a spaceship. Here is the longest partial result:

Assuming there are no bugs in qfind v2.2 (certainly not guaranteed), this means there are no width 20 symmetric (1,0)c/8 ships.

I will hopefully start p9 k2 w9 u, but I'll have to stop if for any reason it tries to crash my computer (w9 searches have done that on occasion to me in the past).

That's alarming. You should use the dump state feature, which will save the progress of the search. If it does crash, it would be nice if you could send me the last saved state so I can experiment with it. If you are willing to crash your system on purpose, you could also try continuing the search from the last saved state to see if it crashes quickly (i.e. before it gets to the next save point). This could indicate that the program is crashing at a particular point in the search.

I'm mostly exaggerating. I've never actually had my computer crash from running a w9 search, but on occasion my computer has begun to behave erratically (freezes in other applications and the like) during w9 searches, especially when I have had multiple running at once, causing me to believe, possibly incorrectly, that a crash was possible. I would suspect that such behavior is the result of other applications' behavior with reduced available RAM, rather than zfind's behavior at high widths.

EDIT: A c/4 pushalong, nothing too important, but some of the components might be useful:

I apologize for the plaintext, which was necessary as a result of transcribing a displayed JLS search state without access to Golly and adding a c/4 ship transcribed from LifeViewer.

I believe the bottom half can act as a pushalong in a similar manner to the above one, but I can't confirm this.

EDIT 3: A surprisingly long c/19 partial:

It's a long shot, but if some pseudo-p19 slide-gun-esque contraption could be created to edge-shoot the correct phi spark to continue the front half of the partial, then a very interesting pattern could be created that has no analogue, as far as I know, currently.

I assume that this is where you originally found the partial result that you used for your ship. Interestingly, the post you quoted contains a tagalong that can be completed with the same small component you used to complete your ship. This gives new 59 and 65 cell ships:

There certainly are such things. My JLS-fu isn't very good, and asking JLS for symmetrical tagalongs with ON cells on or near the axis and two rows behind the base of the A ... immediately returned with "0 solutions".

But ON cells farther from the axis quickly turned up solutions like this:

The second one from the right is the shortest that JLS could find at that width; below that it returned zero solutions fairly quickly again. The rightmost tagalong was found by widening the search area by two cells while shortening it by one cell.

I vaguely suspect there is no 2c/4 level back (and thus no convex corner for that 2c/1 sideways slope meeting itself). There are however definitely 4c/8 level backs. The thinnest of those I've found so far:

No luck connecting them to a back corner yet, although I only tried a very little and only for the best looking one. 4c/8 is really quite painful.

I also have some ideas about trying to find a level back with a very thin connection to itself (and thus better hope of connecting to a back corner). Searches in progress, TBD.

...

Agreed! There must be some solution more amenable to 2c/4 connection. I had something similar with the chicken wire agar, if you remember.

Ordinarily the way to find out whether something is known or not is to check the jslife collection for those periods. So first you have to find the periods. The three smoky ships above are p12, p24, and p48 respectively.

Sokwe maintains a Github repo with sometimes-updated jslife-moving stamp collections. Here are the ones for p12, p24, and p48.

It looks like smoky spaceships aren't really being collected at the moment, for any of the three periods. For example there's a Schick engine in the p12 stamp collection but no modifications of it. There are a lot of p24 rakes and puffers shown, but no p24 spaceships based on Schick engines. I think that's deliberate, because there would be so many of them, with sizes very similar to what you could get by modifying one of the existing rakes or puffers.

Similarly, there are ways to get p48 without adding a second Schick engine. For example, you could add just one *WSS to suppress the output of one of the p48 rakes in the stamp collection.

The "Forward Rake" is a lot larger than p48 forerakes already in the p48 collection. It should be possible to find thousands of other examples at similar sizes.

The p24 backrake is similar. There doesn't seem to be a reason to prefer the new rake to the south, below, to the known rake to the north:

The p12 backrake might be worth adding to jslife-moving, though I'm just guessing here -- Sokwe will know better what the current standards are for adding to those stamp collections. Existing p12 backrakes seem to have a minimum population of 86 (see the pattern to the south, below) -- where the new one (to the north) has a minpop of 77:

Before posting more rakes along these lines, it's probably a good idea to do these kinds of comparisons with existing rakes. If there's no size or population improvement over what's in jslife-moving, then there are probably lots of other candidates with the same size and same period. If people go ahead and post all of those, this thread will get awfully cluttered.

Improvements to both population and bounding box from swapping out the above p4 support with HWSSs and running predecessor searches:

This implies a new 50-cell 2c/4 spaceship using a known p2 component:

This is tied with the other smallest ship that uses this p2 component and so is just small enough to go in the small c/2 ships collection.

At least it's non trivial and p8. I'm desperately in need of a version of wls that can search on odd-odd connections. With the current version, only odd-even or even-even is possible.
