And here i need help. Let's construct a 4-Fireship-gun with a period of 864. With a p200-rake at its head and a Herschel-eater at its feet you get a growing Herschel-conduit (and a breeder) made only from Fireships and Blocks. I have no clue to build such a gun with Fireships so close to each other...

Here's the circuit so far, just missing the NW shotgun and a few small pieces of timing circuitry to tie everything together after it's all tightened up: I made the NW shotgun, so only those pieces of timing circuitry are left: x = 2532, y = 2171, rule = LifeHistory .C$2.C$3C105$107.C$108.2C$107.2C...

I finally made an (inexpertly coded) arbitrarily-large-greyship-synthesising script!: #synthesise-greyships.py #Goldtiger997, October 2021 import golly as g import webbrowser d = 6032 Goffset = 11 t = [[-1,1],[1,1],[1,-1],[-1,-1]] #[NE,NW,SW,SE,xoffset,yoffset] X = ["2$b2o$obo$2bo5b2o$9b2o$8bo7$2bo$...

I made an update to the toolkit to go with my recent update to the H-to-G collection: x = 1601, y = 1147, rule = LifeHistory 1380.25D$1380.25D$158.9D352.9D457.25D370.25D$156.13D348.13D455.25D 370.25D$154.17D344.17D453.25D370.25D13.9D$153.19D342.19D452.25D370.6D 15.4D10.14D$152.21D15.6D319.21D15.9D12...

Dialing down the ambition a little, just cross-checking with Elementary Conduits and adding everything that has been found since 2016 to the stamp collection at the top of this thread, would be a great start -- would make it much easier to look up timing/lane combinations]. I went ahead and added a...

I made a 2c/3 wire receiver with repeat time 964 (using a honeybit bait which was originally posted by calcyman on Discord), which is a long way from 447 ticks, but at least it breaks the 1000-tick barrier for the first time: x = 482, y = 549, rule = LifeHistory 356.2A$356.A.A$358.A4.2A$354.4A.2A2.A...

I made an RRO, which is quite similar to the recently constructed self-synthesising oblique-loopships . However, the RRO is not quite self-synthesising, though it would possible to make it so with some fairly small modifications. The following RRO has a period of 289487508: RRO.mc Here's the above R...

Might a little hunting around with spark_search find a cheaper high-clearance conversion for this step, or has that already been tried? Yep, I found the following component for adding the boat-tie which is a lot cheaper: x = 89, y = 62, rule = B3/S23 20bo13bo$19bobo11bobo$20bo13bo$21b3ob2ob2ob3o$23...

I made a gun for the self-synthesising spaceship: self-synthesising-spaceship-gun.mc It runs quite slowly on my computer, so I haven't been able to properly verify that it continues working forever. The spaceship that is constructed by the gun is slightly different from the spaceship that I posted e...

Let's make sure we have the spaceship itself all figured out first. I've only gotten as far as analyzing the self-synthesizing-spaceship-smaller-again.mc pattern so far, and it's not quite a spaceship -- or rather, I think it's a growing-slowing spaceship (288 ticks slower with each cycle). Good ca...

Using dvgrn's very helpful blueprint, I was able to make a self-synthesising spaceship! If I calculated correctly, the velocity is (16461366,16461323)c/81569531, which also makes it a fast (very slightly) oblique spaceship: self-synthesising-spaceship-smaller-again.mc I did diverge from the blueprin...

I tried backtracking the second greyship recipe using the Official Canada Greyship Component Collection, but I could only make it two steps backward before there seem to be weird specialty top-of-the-ship-only recipes to twist things out of the way, that aren't shown in the collection Yeah, the Com...

This is a really impressive construction. One thousand four hundred and twenty-eight congratulations! Thank you! Once we synthesise the next-size-up greyship, I think we should have all the pieces to synthesise arbitrarily large greyships... I'm still not completely sure about this, so I will check...

This should be a complete synthesis of the "next-size-up" greyship, starting from an xs156 which was synthesised as part of the Canada Grey synthesis: x = 21769, y = 106, rule = B3/S23 21707bo$21705bobo$21706b2o4$21683bo10bo41bo10bo$21681bobo11b2o9bo27b2o 11bobo$21682b2o10b2o4bo6b2o16bo4bo4b2o10b2o$...

Once we synthesise the next-size-up greyship, I think we should have all the pieces to synthesise arbitrarily large greyships. Here's a final step for that greyship for reference:... I've made some progress on the synthesis: x = 9859, y = 62, rule = B3/S23 30bo13bo85bo13bo85bo13bo85bo13bo85bo13bo85...

There was a missing beehive in the 8th frame from the right. After amending, Catagolue says 753 gliders -- very well done!!! Thank you! I made a continuous synthesis which I think looks pretty cool: x = 3202, y = 3200, rule = B3/S23 3157bobo$3157b2o$3158bo4$11bobo11bo3143bo11bobo$12b2o9bobo3131bo11...

This reduces the problem to synthesizing empty space, which can be trivially done in zero gliders: Great! The following should be a complete synthesis of the small greyship: x = 15011, y = 80, rule = B3/S23 14957bo$14955bobo$14956b2o4$14933bo10bo41bo10bo$14931bobo11b2o9bo27b2o 11bobo$68bo33bo14829b...

I think what we need is a set of components to construct arbitrarily large patches of agar. This pair of components can be used for that purpose, though complications do arise on the edge of the agar: x = 100, y = 29, rule = B3/S23 12b2ob2o75b2ob2o$12b2obo76b2obo$17bo79bo$10b8o72b8o$10bo2bo76bo$16b...

I finally completed the final step for the greyship synthesis!: x = 163, y = 118, rule = B3/S23 71bobo$72b2o$72bo4$47bobo11bo39bo11bobo$48b2o9bobo11bo27bobo9b2o$48bo 11b2o3bo5bobo18bo4bo3b2o11bo$54bo11b2o4b2o16b2o3b2o11bo$52bobo10b2o24b 2o3b2o10bobo$53b2o7bo37bo7b2o$60bobo37bobo$61b2o37b2o$54bobo49b...

I solved the back corners of the first greyship I posted, so all that's needed to complete a greyship synthesis final step is a synthesis of the front!: x = 139, y = 83, rule = LifeHistory 45.A47.A$46.A45.A$35.A8.3A45.3A8.A$33.A.A67.A.A$34.2A67.2A2$37.A.A59. A.A$38.2A59.2A$38.A27.D5.D27.A$64.2D3.D3....

Without too much understanding about how syntheses work. I would think smaller is better. But WLS can come up with variants quite easily. What would be a preferable form? Yes, smaller is better. Including recognisable bits such as xWSSs and not being too horizontally thick is also desirable. Other ...

After some experimentation, I've become more optimistic about the possibility of a greyship synthesis. Looking through jslife-moving , the following greyship looked the most feasible to synthesise: x = 107, y = 62, rule = B3/S23 46b3o3b3o$45bo2bo3bo2bo$48bo3bo$48bo3bo$48bo3bo2$46b3o3b3o$47bo5bo$47b ...

Congratulations! This is the second c/4 orthogonal ship to be synthesised. Those two c/4 spaceships are a little less lonely now, because I found a 152-glider synthesis for xq4_y2oo7t0t7ooz2qgx8t2rgr2t8xgq2z122166y5661221, which has already been noticed and slightly improved by users on the Discord...

xs12_3123c4go and xs12_8o6413z32 in 6G and 5G respectively:
I believe that means 12 in 7 is done!
