## c/3 grey ships

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

### c/3 grey ships

In 2006, I started creating grey ships and shortly worked on c/3 grey ships. It is pretty easy to find parts for grey ships because of the small period and the wealth of short wide components. Here is one of the first examples I created:

`x = 309, y = 152, rule = B3/S237\$43bo\$42bobo\$41b2o\$42bobo\$42b2o6b3o7bo6b3o7bo6b3o7bo6b3o7bo6b3o7bo6b3o7bo6b3o7bo6b3o7bo6b3o\$45bo4b2o7bobo5b2o7bobo5b2o7bobo5b2o7bobo5b2o7bobo5b2o7bobo5b2o7bobo5b2o7bobo5b2o\$41bo2bo7bo6b2o8bo6b2o8bo6b2o8bo6b2o8bo6b2o8bo6b2o8bo6b2o8bo6b2o8bo3b2o\$40bo8b3o3bo3bo6b3o3bo3bo6b3o3bo3bo6b3o3bo3bo6b3o3bo3bo6b3o3bo3bo6b3o3bo3bo6b3o3bo3bo6b3o4b3ob2o\$39b2o7bo5b2o4bo4bo5b2o4bo4bo5b2o4bo4bo5b2o4bo4bo5b2o4bo4bo5b2o4bo4bo5b2o4bo4bo5b2o4bo4bo5bo4b2o\$40bo3bo2b8ob2obobo3b7ob2obobo3b7ob2obobo3b7ob2obobo3b7ob2obobo3b7ob2obobo3b7ob2obobo3b7ob2obobo3b13o3bo\$39b3o4bo8bo7bo8bo7bo8bo7bo8bo7bo8bo7bo8bo7bo8bo7bo8bo7bo14b2obo\$37bob2ob2o2b10o3b14o3b14o3b14o3b14o3b14o3b14o3b14o3b20o\$37bo3bo158bo\$37bo3b158o5bo\$28bo7bob2o161bobo\$26b2o6b2ob2ob160obo2bo\$26b2o5b3o3bo164bo\$32bo3b168obo\$27b3o2b2obo173b2o\$27b3o3bo2b170o3b3ob2o\$33b2o172bo4b2o\$24b3o7b180o3bo\$24b3o187b2obo\$32b183o\$23bo3b2ob2o185bo\$24bo2bo3b185o5bo\$21b2o195bobo\$21b2o2b192obo2bo\$12bo7b2o2bo196bo\$11bobo4bo3bo2b196obo\$11b2o5bo207b2o\$11bo5bo3b202o3b3ob2o\$12bobo2b4o203bo4b2o\$12bobo5b211o3bo\$10b4o4bo212b2obo\$9bobo6b214o\$9bobo222bo\$9b4o3b217o5bo\$12b2obo219bobo\$7b2o3b2ob219obo2bo\$6b3obo3bo223bo\$8bob228obo\$5bo2b2o233b2o\$4bobo3b230o3b3ob2o\$2b2o2bo234bo4b2o\$2bo2b243o3bo\$2b3o243b2obo\$2bo2b244o\$3bo247bo\$3b247o5bo\$252bobo\$3b248obo2bo\$3bo251bo\$2bo2b250obo\$2b3o255b2o\$2bo2b252o3b3ob2o\$2b2o2bo251bo4b2o\$4bobo3b255o3bo8bo\$5bo2b2o255b2obo7bo\$8bob256o9b2o11bo3bobo\$6b3obo3bo253bo6bo5b2o2bob2o3b2obo\$7b2o3b2ob252o7b4o3b2o2bob4o\$12b2obo253bo3bo10b2o3b2o\$9b4o3b252obo3b11o8bo2bo\$9bobo274b4o3bo2b2o\$9bobo6b269ob2o2b2o\$10b4o4bo274b2o\$12bobo5b270o\$12bobo2b4o272b2o\$11bo5bo3b266ob2o2b2o\$11b2o5bo267b4o3bo2b2o\$11bobo4bo3bo2b243obo3b11o8bo2bo\$12bo7b2o2bo244bo3bo10b2o3b2o\$21b2o2b242o7b4o3b2o2bob4o\$21b2o245bo6bo5b2o2bob2o3b2obo\$24bo2bo3b235o9b2o11bo3bobo\$23bo3b2ob2o233b2obo7bo\$32b233o3bo8bo\$24b3o231bo4b2o\$24b3o7b223o3b3ob2o\$33b2o225b2o\$27b3o3bo2b219obo\$27b3o2b2obo219bo\$32bo3b215obo2bo\$26b2o5b3o3bo212bobo\$26b2o6b2ob2ob210o5bo\$28bo7bob2o211bo\$37bo3b208o\$37bo3bo206b2obo\$37bob2ob2o2b202o3bo\$39b3o4bo194bo4b2o\$40bo3bo2b193o3b3ob2o\$39b2o7bo5bo188b2o\$40bo8b3o4b182obo\$41bo2bo7bo3bo5bo175bo\$45bo4b2o5b3o4b170obo2bo\$42b2o6b3o7bo3bo5bo164bobo\$42bobo13b2o5b3o4b161o5bo\$41b2o15b3o7bo3bo5bo155bo\$42bobo21b2o5b3o4b152o\$43bo22b3o7bo3bo5bo144b2obo\$74b2o5b3o4b143o3bo\$74b3o7bo3bo5bo129bo4b2o\$82b2o5b3o4b127o3b3ob2o\$82b3o7bo3bo5bo123b2o\$90b2o5b3o4b117obo\$90b3o7bo3bo5bo110bo\$98b2o5b3o4b105obo2bo\$98b3o7bo3bo5bo99bobo\$106b2o5b3o4b96o5bo\$106b3o7bo3bo5bo90bo\$114b2o5b3o4b87o\$114b3o7bo3bo5bo79b2obo\$122b2o5b3o4b78o3bo\$122b3o7bo3bo5bo64bo4b2o\$130b2o5b3o4b62o3b3ob2o\$130b3o7bo3bo5bo58b2o\$138b2o5b3o4b52obo\$138b3o7bo3bo5bo45bo\$146b2o5b3o4b40obo2bo\$146b3o7bo3bo5bo34bobo\$154b2o5b3o4b31o5bo\$154b3o7bo3bo5bo25bo\$162b2o5b3o4b22o\$162b3o7bo3bo5bo14b2obo\$170b2o5b3o4b13o3bo\$170b3o7bo3bo5bo4b2o\$178b2o5b3o4b3ob2o\$178b3o7bo3b2o\$186b2o\$186b3o!`

Later on, I added a part for getting a perpendicular front. Using these parts in combination many slopes at the front can be realised:

Note that all the parts used can be plugged together quite arbitrary because of the common interface. This small interface is also the key to finding the parts with wls.

Steeper versions can only be found with custom connections. Here is the steepest descent I could find so far.

The challenge is now to find steeper parts and find the maximum slope that is attainable with period 3.

### Re: c/3 grey ships

Have you found any components where the stripes are perpendicular to the direction of the ship?

### Re: c/3 grey ships

for c/3, this would only be possible for period 6! This is pretty much at the limit of current search programs.

But so far no idea how to build a complete grey ship from these components!

Well, you can't extend it so it isn't really a greyship. I call this type of ship mini-grays

### Re: c/3 grey ships

HartmutHolzwart wrote:<snip> c/3 greyships </snip>

However, at the backend, the descent is not very steep. Here is a slightly steeper descent:

`<snip> rle for c/3 greyship with backend slope of 5/6 (10/12) </snip>`

Note that all the parts used can be plugged together quite arbitrary because of the common interface. This small interface is also the key to finding the parts with wls.

Steeper versions can only be found with custom connections. Here is the steepest descent I could find so far.

`<snip> rle for c/3 greyship with backend slope of 6/5 (12/10) </snip>`

The challenge is now to find steeper parts and find the maximum slope that is attainable with period 3.

Here is a c/3 greyship with backend having slope of 4/3 (16/12):
`x = 207, y = 137, rule =

I was able to reuse the custom corners from the ship above for the inner part of the 16/10 component, but had to find additional stabilisations for the outside part.

Unless I am mistaken there is no steeper p3 backend with spatial period of < 12. I believe any steeper components are going to become successively larger and more complex, but there might be something surprising out there. I haven't searched for 18/12 components which would give a slope of 3/2 - this might be a good space to search.
The latest version of the 5S Project contains over 196,000 spaceships. Tabulated pages up to period 160 are available on the LifeWiki.

### Re: c/3 grey ships

Great work! Good to see someone else working on grey ships again.

Somehow related:

Here is an example of a c/4 grey ship, featuring one new part and a few new connections of old parts.

However, at the backend, the descent is not very steep. Here is a slightly steeper descent:

`<snip> rle for c/3 greyship with backend slope of 5/6 (10/12) </snip>`

Note that all the parts used can be plugged together quite arbitrary because of the common interface. This small interface is also the key to finding the parts with wls.

Steeper versions can only be found with custom connections. Here is the steepest descent I could find so far.

`<snip> rle for c/3 greyship with backend slope of 6/5 (12/10) </snip>`

The challenge is now to find steeper parts and find the maximum slope that is attainable with period 3.

How did actually find that part?

Here is a c/3 greyship with backend having slope of 4/3 (16/12):

I was able to reuse the custom corners from the ship above for the inner part of the 16/10 component, but had to find additional stabilisations for the outside part.

Unless I am mistaken there is no steeper p3 backend with spatial period of < 12. I believe any steeper components are going to become successively larger and more complex, but there might be something surprising out there. I haven't searched for 18/12 components which would give a slope of 3/2 - this might be a good space to search.

I used both JLS and WLS-nb with toroidal boundary conditions + shift for the top/bottom edge I can't remember which one actually came up with the solution and I didn't keep many search files along the way, but I've attached one of my In Progress files from WLS-nb which illustrates the search. You'll note in the original search state that the width is 16, the shift is 12 and there are at least 12 columns of 'Don't Care' cells and twelve columns of stripes agar. These are necessary to match up the shifted top and bottom edges and also to prevent errors in the initial search state. I've introduced anisotropy with a single On cell in one of the Off rows.
