Alternate back edges to the recent c/4 diagonal puffer engine with slightly different sparks could give variant puffer engines that behave differently. Here are two related partial results, the first probably being easier to solve, but the second giving a more resilient engine: x = 168, y = 29, rule...

Just a few minutes later one of the other searches dropped this: #C [[ TRACK -1/4 -1/4 ]] x = 74, y = 102, rule = B3/S23 28b2o$28bobo$28bo$31bo$31b2o$31b2o$30b2o$26b2ob2o$26bo4bo$26bob4o$30b 2o$31bo$30b2o$26b4obo2bo$25b2obobobo$27bo4b3o27b2o$50b3o9bobo$32bo17bo 2b3o6bo9bo$7b3o41bobo16b2obo$7bo22b2o...

I guess it just seems rather hemmed in, stuck searching upward, and subjectively the rate at which search results were lengthening with widening windows seemed poor. Alas it's crummy subjective metrics all the way down. I feel like it wouldn't be too hard to move that center branch out of the way o...

I don't think this is useful, but the smoke can reflect a glider (of course, the glider would need to be placed there very precisely): x = 74, y = 102, rule = B3/S23 28b2o$28bobo$28bo$31bo$31b2o$31b2o$30b2o$26b2ob2o$26bo4bo$26bob4o$30b 2o$31bo$30b2o$26b4obo2bo$25b2obobobo$27bo4b3o27b2o$50b3o9bobo$3...

That sparker with that clearance is quite demanding. Some preliminary searches (8 GB) do find longish partials but they don't look very nice to me (mostly wide and mostly getting wider as they go), e.g.: x = 74, y = 53, rule = B3/S23 28b2o$27b2o$29bo$31b2o$30bo2$29bo2bo$26b2obo$25b2o4bo$27bobo2bo$3...

Here's an idea for a p12 c/4 diagonal backrake that might be possible, but it would require the discovery of multiple, likely difficult components: x = 265, y = 57, rule = B3/S23 28b2o68b2o68b2o68b2o$27b2o68b2o68b2o68b2o$29bo69bo69bo69bo$31b2o68b2o 68b2o68b2o$30bo69bo69bo69bo2$29bo2bo66bo2bo66bo2bo...

Here's some detail on how I found the recent puffer engine, for those who are curious. The partial result posted here was found with JLS . I first tried to find a puffer that emits a 4-line (beehive predecessor). Nothing I tried was working. I then remembered how a pre-TL can sometimes interact with...

Here's an idea for a p12 ( Edit: originally I incorrectly claimed it was p16) c/4 diagonal backrake that might be possible, but it would require the discovery of multiple, likely difficult components: x = 265, y = 57, rule = B3/S23 28b2o68b2o68b2o68b2o$27b2o68b2o68b2o68b2o$29bo69bo69bo69bo$31b2o68b2...

Here is a diagonal c/4 period 52 rake Wonderful! When I first found the engine, I was excited to see that it seemed to have a base period of 52 and was hopeful that such a rake could be constructed. It turned out more difficult than I anticipated. I took the liberty of compacting the components of ...

For the same reason that Antonin believes they should be posted in a separate thread. I didn't, and still don't, understand those reasons. I would probably need it explained in a different way. Right now I don't see how the c/4 diagonal posts negatively impacts the posting of other content. Also, i...

Here is a pretty dirty diagonal c/4 period 52 based puffer, at least near the engine. I haven't looked at taming the exhaust. Big glider can provide a functionally equivalent spark while giving a bit more room for sparkers at the back: x = 80, y = 62, rule = B3/S23 27b3o$27bo$28bo$30b2o$31bo2$28bo$...

I also believe that the c/4d technology should be moved to another thread, but refused to say it on the forums until someone else posted about it. The c/4d technology posts currently in the Spaceship Discussion thread should be kept there, but the new ones should go in a new thread Can you give mor...

The one front branch is easy, even with okayish clearance... And the second branch wasn't that bad either. As pictured the smoke does destroy the engine so I guess it's time to play spark guess and check... One solution Excellent! This is only the third c/4 diagonal puffer engine (after the p28 eng...

Well usually we see a variety of speeds being posted, like c/2o, c/3o, 2c/5o, c/5d etc., but now it's just one speed, and that's c/4d. I don't see how the c/4 diagonal discussion would prevent other speeds from being posted. This thread is usually fairly inactive until some new result spawns a flur...

I think it should.

Can you give more details on why? I'm still not convinced there is a problem with the current situation. I'd also be interested to hear from anyone else.

By the way, when this is resolved I'll move all this meta-discussion somewhere else.

Guys, shouldn"t all of this c/4 diagonal technology be moved to a separate thread? Is that something people want? I don't personally see the problem with the current situation. The spaceship discussion thread doesn't seem to be getting much use otherwise at the moment, so the c/4 diagonal content d...

Amling, when you get a chance, could you try to complete this potential c/4 diagonal puffer engine (shown here at 4-generation intervals): x = 556, y = 44, rule = B3/S23 9bobo37bobo37bobo37bobo37bobo37bobo37bobo37bobo37bobo37bobo37bobo37bob o37bobo37bobo$7b3o37b3o37b3o37b3o37b3o37b3o37b3o37b3o37b3o3...

A p20 c/4d spaceship might be possible by modifying the p28 puffer. Here is a way that a spark could theoretically be provided at c/4d that would result in a p20 spaceship: Is there some trick to finding these things? Is it just guess and check by simulating in golly, sparking by hand? Yes, guess a...

Here is a (probably useless) p16 c/4 diagonal blinker puffer created by perturbing the p8 backrake glider stream with sparkers: x = 152, y = 153, rule = B3/S23 70bo$69b2o$69bob3o$73bo$68bo$65b4obobobo$65bo5bo2bo$66bo2b4o$65b2o2b2o $59b2o4b2o$59bo2bo2b2o$49bo3bo4bo2b2o2bo2bo$48b5o2bobo4bo2bo$48bo6b3o...

Here's a p24 rake: Packed: Beehive-to-ship-to-loaf-to-loaf-to-glider is a rather roundabout way to get there, but it gets the job done. Excellent! If we use the faster loaf deletion the beehive-to-...-to-glider converter can work as low as period 20: x = 170, y = 190, rule = B3/S23 bo$obo$obo$bo$55...

I want to point out something in particular from the above c/4d eater reference that hasn't been mentioned before. There are three closely related sparkers that can be given one more half-diagonal of clearance: x = 199, y = 93, rule = B3/S23 32b2obo66b2obo66b2obo$32bo3bo65bo3bo65bo3bo$32bo4bo64bo4bo...

c/4 Diagonal Eater and Converter Reference This post is meant to be a reference for the various c/4 diagonal eaters and converters found over the last few months. Object Lists Below is a list of some small objects that can be eaten by c/4 diagonal ships. The list accounts for orientation, so otherw...

I confess I don't follow how we'd expect 84 = 3x28 or 108 = 3x36 as they're not multiples of 8 and so LCM with p24 is bigger. Is there some non-p8-requiring trick upthread I've forgotten? There are so many to keep track of... I wasn't really thinking about it too closely. I suspect that some unique...

I am the original poster of the double beehive push, as far as I know. oregan0 on discord. Sorry, I'm confused. Are you saying that you are the discoverer and oregan0 is your Discord username? Also, can I get a link to where the pattern was first posted on Discord and where it was first posted on t...

Might anybody be interested in running the various highly speculative drifter searches starting from a pair of double-length signals converging on one location? Or some way of combining the various sparkers that we can attach to the output end of a 2c/3 wire? It would be very entertaining if it was...
