Now, as far as I know, the two smallest un-buildable spaceships are the 29- and 30-bit c/3 ones. Indeed. I think the following are all of the known ships with no known synthesis up to 36 cells: x = 158, y = 213, rule = B3/S23 29bo$27b2o$27b2o$29bo$27bo$obobo3bobobo13b3o$26bo$4bo3bo3bo12b2o$28bo$ ob...

xs20_4aab8n96zx32 in (probably) 9 gliders You can actually skip the constellation and get the starting reaction from 3 gliders.

seven period shifts comibined with some spatial shifts. Here is a clean p14... Interesting idea, although the period is 26. The fuse travels at 6c/13. The blinkers can also be out of phase, allowing more combinations: x = 29, y = 188, rule = B3/S23 7b3o9b3o$7bobo9bobo$6bo2bo9bo2bo$6bob4o5b4obo$4b2o...

Catagolue erroneously reports a p182 puffer. It's actually the p14 3c/7 blinker puffer followed by a 12c/26 fuse: x = 29, y = 188, rule = B3/S23 7b3o9b3o$7bobo9bobo$6bo2bo9bo2bo$6bob4o5b4obo$4b2o4bobo3bobo4b2o$5b3ob 2obo3bob2ob3o$3bo8bo3bo8bo$3bobo2b2obo5bob2o2bobo$2bo3b2o4bo3bo4b2o3bo $3bobo5bo5bo...

P14 3c/7 blinker-pair puffer found by Dylan Chen, the lowest-period 3c/7 linear-growth mechanism so far Very nice! Based on this and a suggestion by Hartmut Holzwart to look at different ways to stabilize the p28 wave, I was inspired to find these new puffers (periods 28 and 84): x = 284, y = 256, ...

Thanks for taking the challenge! Would your end piece work with odd width as well? I need two different backends for odd and even widths. For higher widths, much steeper descents should be possible!Optimizations welcome, obviously! Here is a width 11 chicken wire spaceship. There is one new compone...

Crosspost from Discord: Adam P. Goucher used ikpx2 to complete a 2c/5 ant waveguide based on a partial result I had provided (left-hand waveguide by Nicolay Beluchenko, 8 Nov 2008): x = 125, y = 127, rule = B3/S23 113b3o3b3o$112bo3bobo3bo$112b2o7b2o$112bo3bobo3bo$113b2o5b2o$110b3obo 5bob3o$110b2ob2o...

When I try this, the search quickly widens to well outside of a reasonable search width. I'm going to guess that it's because of the spaghetti monsters. Even without the spaghetti monsters, the search needs to be started several rows above the tail of the gutter tagalong. I'm wondering if there is ...

Is there a way to set up an ikpx2 search to find these and potentially other solutions? I believe it is possible with the -m flag (how I set up ikpx2 for Anura tagalongs). Just place two heads together and initiate ikpx2, passing the Y-value to the -m flag. I can't seem to get it to work. As far as...

Here's a way of supporting the front half of the new ship using spaghetti monsters Some quick qfind searches were able to find a few ways to extend this to a wave: x = 176, y = 137, rule = B3/S23 10bo7bo138bo7bo$8b2ob2o3b2ob2o134b2ob2o3b2ob2o$8b2ob2o3b2ob2o134b2ob2o 3b2ob2o$11b2o3b2o140b2o3b2o$7bo5...

Is there any way to get this back into Lifeland? It's so close!

That's a good partial result! I suspect that playing around with adjusting and tapering the rotor search area should yield a complete sparker.

The yl70 haul finally got uploaded Awesome! With all the sparkers we now have, I suspect we can perturb it to get some interesting puffers and maybe even some new rake periods. Speaking of sparkers, the new ship can support the p28 wave: x = 87, y = 75, rule = B3/S23 10b3o5b3o$10bobo5bobo$10bobo5bo...

Your excellect program found another 3c7 spaceship. This allows the construction of a p21 rake: x = 72, y = 246, rule = B3/S23 23bo11bo$22bobo9bobo$21b2ob2o7b2ob2o$21bo15bo$21b3o2bo5bo2b3o$19bo7bo 3bo7bo$20b2o2b2ob2ob2ob2o2b2o$20bobo4bo3bo4bobo$17b3ob3o2b2o3b2o2b3ob 3o$17b2ob4ob3o3b3ob4ob2o$18b4o4b...

Nothing very interesting here. I just rearranged some of the parts to reduce the size of the 3c/7 p21 ship and p84 rake. Due to their large size, I optimized for bounding box rather than population. p21 3c/7 spaceship: x = 133, y = 401, rule = B3/S23 18b3o9b3o$17bo3bo7bo3bo$16bobo3bo5bo3bobo$16bo3b2...

Amazing! What are the the tools you used for finding these? Assuming you're talking about the rake, I didn't use any sophisticated tools. I just tried various spaceship placements by hand in Golly, so my search was not thorough. I'm still hopeful that someone will find a period-21 rake. Edit: Chris...

Here's a clean period-84 3c/7 rake based on the above period-21 spaceship: x = 169, y = 645, rule = B3/S23 19bo11bo$18bobo9bobo$17b2ob2o7b2ob2o$17bo15bo$17b3o2bo5bo2b3o$15bo7bo 3bo7bo$16b2o2b2ob2ob2ob2o2b2o$16bobo4bo3bo4bobo$13b3ob3o2b2o3b2o2b3ob 3o$13b2ob4ob3o3b3ob4ob2o$14b4o4b2o3b2o4b4o$15bo5b2o5b...

So far I can only make the mess worse instead of better, but I haven't tried all the options yet, or even close. It seems like a p21 rake must be out there somewhere... Interesting ideas. Maybe someone can draw inspiration from this period-21 spaceship: x = 167, y = 530, rule = B3/S23 18bo11bo$17b3...

The loafer has been known since 2013, it has certainly been known that a loafer could appear from a 16×16 soup because a loafer fits inside that bounding box (and because of one of Dave Greene's 2018 April Fools' Day pranks), and it has certainly been known that spaceships can appear from soups.
