For discussion of specific patterns or specific families of patterns, both newly-discovered and well-known.

I noticed that one of Tim Coe's new p8 c/4 orthogonal ships has an isolated p8 spark:
x = 31, y = 15, rule = B3/S2310b2o6bo10bo$5b3o2b3o15b2o$7bo2b2obobo11b2obo$5b2o5b3o8b2obobobo$b2o2bo2b3obo3b5o5b2o2bo$2ob2o5bo4b2o5bo4b2obo$bo3bo9bo6bo2bo2b2o$2o3bo17bo2bob3o$bo3bo9bo6bo2bo2b2o$2ob2o5bo4b2o5bo4b2obo$b2o2bo2b3obo3b5o5b2o2bo$5b2o5b3o8b2obobobo$7bo2b2obobo11b2obo$5b3o2b3o15b2o$10b2o6bo10bo!

I had thought that this spark was period-4. Using a known trick, I isolated the spark further. This allowed a small interaction with the block deletion in the p20 and p28 ships, resulting in nontrivial p40 and p56 ships:

The reason for all of these c/4 orthogonal results is that I have been working on my update to jslife, and have added a c/4 orthogonal extended collection. Looking back through old technology gave me some new ideas. I am now done updating all of the collections of moving objects in jslife except c/3 orthogonal. Also, thanks to Dave Greene's Life Lexicon update, I noticed this c/4 orthogonal ship (by Nicolay Beluchenko) that should have been in the small ships collection: x = 25, y = 23, rule = B3/S2322b3o2$22bobo2$20b2o$19bobo$17bob2o$16b2o3bo$11b3o$14b2o2bobo$12bo6bo$11bo$9bobo$8bob2o$8b2o$9bo$bo5bobo$bo7bo$obo4bob2o$10bo$5bob3o$b5obo$2b2o2bo!

I've finally completed my update of the jslife moving objects collection (Edit: this file is old. Please use the link above):
jslife-moving-objects-update-3sep2017.zip

This is a fairly comprehensive collection of elementary-based moving technology. Caterpillars, Caterloopillars, half-baked ships, and Geminoids are not included in this collection.

Please let me know If you find any errors, omissions, or inconsistencies.

I will also include a link to this post at the beginning of the topic.

Thanks a lot for compiling this collection, it's great to have.

I don't know if this counts as an omission in the strict sense, but one thing I'd love to see is information on who first found which ship, when, and so on, in the same manner as in Dean Hickerson's oscillator stamp collection.

I was just looking for Eppstein's glider glider 16485 (that's 70P2H1V0.1 on Pentadecathlon); found it right away, too, in velocity-c2/c2-extended/c2-0002.rle (again, thanks to everyone!), but as there's no meta-information about any of the ships I'm still in the dark about who first discovered it.

Many (perhaps most) patterns in the collection do have that information. That happens to be one of the exceptions. The main reason the information isn't included is that it's just too much work to track down. I spent nearly as much time finding credits for old patterns as I did adding new patterns.

To answer your specific curiosity, 70P2H1V0.1 was found by Hartmut Holzwart sometime in the two weeks preceding 3 July 1992. It was found with the restriction that all on cells have at most 6 on neighbors and all off cells have at most 5 on neighbors. This allows it to work in many different rules, which is probably why David Eppstein included it in his database.

I found the information for this spaceship by first looking at David Bell's article, "Spaceships in Conway's Life (Part 2)" (available from his website). It mentions that Hartmut started searching for p2 ships in June of 1992, and that this specific ship had been found "recently". I then looked at some old email archives to find the specific message in which the ship was posted. Unfortunately, the email archive is not available for public release.

Excellent, thanks for the detective work!

I'm curious, too -- how come the archives aren't available? Wasn't this a public mailing list?

The mailing list was not public. As I understand it, the reason the archives aren't made public is that not everyone on the list has given explicit permission. Since the archives date back to April 1992, it might be hard to even get in contact with some of the members. Dave Greene has more details (sorry Dave).

These archives are basically only useful for finding historical information. Even then, most of the interesting historical information has ended up in publicly-available pattern collections and articles.

This should give rakes of periods 108 and 112 based on the quoted HWSS synthesis. Unfortunately, the synthesis doesn't work at period-92. Is there a 4-sided, 4-glider HWSS synthesis that does work? The minimum period for the HWSS-to-glider reaction is 80, but I don't know of any period-80 fan-out devices. -Matthias Merzenich Sokwe Moderator Posts: 1480 Joined: July 9th, 2009, 2:44 pm ### Re: Spaceship Discussion Thread Here are two closely-related 40-cell c/4 orthogonal spaceships: x = 40, y = 17, rule = B3/S233bo22bo$b2o21b2o$3bo22bo$5b4o19b4o$6bo2bo19bo2bo$7b2o21b2o$8b2o21b2o2$6bo22bo9bo$4b2obobobobo13b2obobobob2obo$5bo5bob2obo11bo5bobo$5bo10bo11bo$5bo3b2o17bo3b2o$4b5o18b5o$2bo22bo$2o21b2o$2bo22bo!

I searched for 3c/10 spaceships for up to w8 in all symmetries with zfind-s, with no success. Here is a selection of partials which contains a few promising ones:

I also searched for 3c/13 ships up to w7 in all symmetries with qfind without success (I didn't outputs partials). I think zfind-s would have been faster(?), so in future I'll use zfind.

Hey, I posted the w8 3c/10 search above already.
I and wildmyron manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules.

Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule
- Finish a rule with ships with period >= f_e_0(n) (in progress)

Oh sorry! I only checked through the spaceship search status page, and didn't check this thread .

On the bright side, at least the result was verified.

Edit: a very minor result, no 5c/11 ships up to w9.

C/9 is negative at w8 for a, v, and u symmetries. I have not done w8 g yet, but w8 v took over one and a half months, so it will be a while. I am running 3c/10 w9 a and v right now, which will take a while.

Good partial from C/9:

3c/10 w9 a and v are negative. I am searching w9 u now, probably be finished in a few days.

@AforAmpere

Thanks for the new results. I had been neglecting the status table for a while, but I have now updated it.

Also, notice that any asymmetric ships will show up in a gutter-symmetric search of the same width, so it usually isn't necessary to run the asymmetric search. Of course, if the gutter-symmetric search finds a ship that is not composed of two asymmetric ships, then you will need to run the asymmetric search.
