I had previously decided not to include them in the jslife-moving collection, because I felt they caused clutter.

It was noted not long after this ship's discovery that two copies could interact nontrivially. I likewise decided not to include these in the jslife-moving collection.

I guess c/4
That particular pull (and one of the others) can be supported at c/3:

however this might be debatable, since no phase contains a block. All four block pulls can be supported at c/4, although two do not contain a phase with a block:

I'm attempting to enumerate all width-10 odd-bilateral c/3 orthogonal spaceships with gfind (without repeating parts, of course.)

EDIT: Halted at length 712 due to duplicates. Can this go into the moving pattern collection?

gfind was not designed for this. Instead you would want to use knightt. In this case, however, the search has already been completed.

I generally keep knightt results separate from the moving object collection. They can be found here.

There is also an old collection of gfind results compiled by Jason Summers and available here (mirrored here).

My reasoning at the time was that fireship is the smallest known spaceship capable of pulling those tagalongs.

There are many reasons why that cannot be made into a ship.
1. That leaves behind a lot of debris.
2. The junk cannot get behind it after 53 gens:

3. That junk reaction probably cannot be made in the 1-glider budget you have

I spent a while trying to combine this with various sparky c/4 diagonal ships to produce different puffer engines, with no luck, despite some heartbreakingly close calls where the sparky ship succeeded in modifying the exhaust but the reaction caught up with the engine from the opposite side and destroyed it. Today, at Kazyan's suggestion, I tried a bit of messing around with JLS to try to find a stabilization with even higher clearance, but after about twenty minutes I discovered that all one of the parts I took from jslife needed was either a domino spark (provided by a B29) or a pair of adjacent dot sparks — which was a connection that could be made from other known parts in jslife:

Code: Select all

Unfortunately, I can't find any way to modify the exhaust of either one further, and a bit of manual soup searching didn't turn up any different orbits, so there still isn't a truly "versatile" puffer engine for c/4 diagonal. Nevertheless, it's certainly progress. Finding one or two more even slightly sparkier c/4 diagonal ships would likely result in, if not an infinite variety of low-period puffers, then certainly a fair number more than are currently known.

This is definitely the sort of thing that should have also been posted here, even if you couldn't find a use for it at the time. The forums are better for archiving this stuff, which could easily get lost and forgotten on the Discord.

I want the entire collection of all 2c/5 ships just to see if this is included:

There is no "entire collection", because there are too many 2c/5 ships to keep track of (likewise with c/3 and c/4). Most known elementary and elementary-based moving objects are contained in the following collections: jslife-moving, knightt results, lots of spaceships, Paul Tooke's puffers, and c/5 rakes. This covers just about all of the elementary spaceship technology deemed by myself to be "interesting". The ships you listed are all contained in each of the first three linked collections.

These ships are also contained in the spaceship collections that come with Golly.

Wow! I think this is the first new c/4 diagonal period achieved since the rake constructions 14 years ago!
How about this
c/4 diagonal
Hmm, I'm not seeing it. All of the technology of periods greater than 4 seems to be from Oct. 2005 or earlier.

This was the essential reaction, I think — there were a number of different ships
Thanks. Unfortunately, it looks unlikely to be fixable for the reason you already mentioned.

### Re: Spaceship Discussion Thread

Congratulations!

Great to finally see progress in diagonal c/4 puffers after so many years!

By now it should be relatively easy to create a script that simulates an incomplete puffer engine to get useful candidates. I remember that finding the first completion of the engine was quite tedious, so you‘d only start when you see that the engine actually produces something new.

Also, there could be low hanging fruits as the field was never explored systematically (as it has been done for low period puffer engines running horizontally).
