Nice one!

It would be interesting to see whether this wave connects to other 2c/5 parts.

Such short wide parts help to complete grey ships.

A 2c/5 ship with even bilateral symmetry (there don't seem to be many of these). There's likely a smaller completion with the same front-end - this is the first (and only) one I found. The front-end came from attempting to stabilize some 2c/5 waves I found (see below).

I spent some time searching for 2c/5 waves as well as other short wide components. I don't seem to have the knack for setting up short wide searches which give results (sorry Hartmut) but here are a few longer waves which use the front-end shown in the first ship of this post:

I managed to stabilise the front connection, as seen above, but I haven't managed to finish the back of any of them. Here's one partial completion, though it's by no means more promising than any other search avenue.

I decided to try a 2c/5 search with ikpx. After several rounds of trial and error with parameters I settled on a width 9 search with lookahead of 60, i.e.

Code: Select all

\$ python ikpx.py -d ~/ikpx/odc5-w9k60 -f p1k60w9 -v 2c/5
No results were found prior to the search widening to width 10 (after about 20 CPU hours) and as far as I can tell, all the partials emitted were various continuations of the same frontend as this one (the longest):

There's no ship I could find with that frontend (except for a 70 cell ship with even bilateral symmetry) so I thought it would be nice to find an asymmetric completion for it. After some JLS-ing and comparison with known ships I found it can exist as a pushalong for a common frontend in the small ship collection. Here is the smallest complete ship with minimum pop of 126 cells.

Code: Select all

x = 55, y = 13, rule = B3/S23

Asymmetric search for c/8 diagonal with width 9 is negative (after a good day of computing). These as the best partials, maybe they can be used to build a symmetric c/8 ship

@2718281828: Hmm, that's not as promising as I hoped it would be considering the jump in width, though gfind and zfind do search very different parts of the search spaces for diagonal ships. Could you please include the program (presumably zfind) and version used to run that search?

I'm not sure that trying to combine asymmetric partials like that is going to be fruitful. I think you're better off running gfind with a symmetric mode instead (or WLS/JLS as they're reported to be faster for diagonal searches).

Not particularly useful but the search process has been enlightening for me. There were many more dead-ends in that search than I care to remember.

Turns out there is a ship with that frontend, or at least most of it. It's in Sokwe's width 13 knightt search results. At the same time I had a look through the other 2c/5 results which I seem to have forgotten about.

I used ntzfind 3.1 for finding these partials. CPU time about 50000s.

I also tried gfind, it allows for symmetric diagonal searches which is nice. But the version that I use does not provide any partials which makes it a bit frustrating to use.

Returning poster on new account (I forgot my old password), first post after years of dormancy.

Here are six new-ish c/3 p3 ships found by mirroring arms and components of existing ships. No scripts were involved, just manual trial and error. I guess you could debate whether they really count as "new", but I couldn't find them anywhere online already and think they look distinct enough to count as something new.

None of them look particularly useful, but for some reason I think the little top-left one is kinda cute. ^_^

From the jslife pattern info:

#CHartmut Holzwart found a way to build a new wickstretcher
#C(22 Apr '05). A stationary part needed to complete the
#Cpattern was first found by Karel Suhajda.
#CThere are many possible variations of the wickstretcher,
#Csome of which are easy to find, and others not.
#COne is shown below, with one-sided stationary
#Cparts found by Jason Summers and Holzwart.

The reason that fails is that the wick used by the front part is actually subtly different from that used by the back (see the moving parts alongside the two-line core).

Yes, that's what I posted.

If someone can find a glider collision that rephases a single component (it can have arbitrarily high repeat-time) in-place, then we can add an assembly of high-period c/2 rakes to incrementally transform the constant-phase wick into the alternating-phase wick, yielding a [pseudo-period] c/2 wickstretcher of the alternating-phase wick.

Then, we actually would obtain a legitimate growing spaceship.
What do you do with ill crystallographers? Take them to the mono-clinic!

Are there any small spaceships that are period 2?
