23-bit still life syntheses

[hkoenig]

I believe that can be reduced by one:

Code: Select all

#C 23_0ck0fpzc9701226
x=38, y=46
2bo$obo$b2o16$19bo6bo$17bobo6bobo$18b2o6b2o2$23bobo$24b2o10b2o$24bo6b2obo2b

o4$21b2o$22b2o$21bo!

#3 is easy with the usual trick

Code: Select all

x = 21, y = 16, rule = B3/S23
8bo$6bobo$7b2o3bo$11bo$11b3o2$2o16bobo$obo15b2o$2bo16bo$b2ob2obo$bo2b

However, despite neither having synthesis displayed on catagolue, these two apgcodes are not in the list of 36 left on the first post of this thread. Could someone check the records for their existence, and confirm that (1) the enumeration of apgcodes of strict 23-bit still lives as synthesis targets had been complete, and (2) obtained batch transfer results had been submitted to repository and viewable on catagolue?

Edit: so this has been explained before in September. Any updates to clear this confusion now that three months have passed?

Shinjuku is a better place to look, as catagolue is not always up to date.

Here are some more broken steps that would lead to solutions. Again there's a mix of plausible-looking to totally impossible, but I'll post them all just in case...

Okay, more than half of the 15-still-life stamp collection have been solved. I'm always puzzled by why unsolved-still-life lists are so rarely maintained for maximum convenience... to me that means a stamp collection with objects in the same order as the apgcode list, and actual links in the list instead of just apgcodes.

The last two unsolved 23-bitters:

Has anyone written the script yet, that grabs the soups from all the links on a Catagolue object page, and sorts them according to how many ticks it takes before the target object first appears in the soup?

[hkoenig]

to me that means a stamp collection with objects in the same order as the apgcode list, and actual links in the list instead of just apgcodes.

An exercise for the student would be to create a script that would take a list of objects (by apgcode, or rle, or whatever encoding appropriate) and produce a stamp collection. For bonus points, add options for number of rows/columns, spacing, breaks, and other pretty formatting options.

Even better would be the ability to embed it into this forum the way LifeViewer is added through the "code" tag.

Such a list would be easier to maintain than a stamp collection because it would be possible to do a diff on two such files, and easily added to a version control system.

The last one, in particular, requires a high clearance component that converts a table motif to a snake motif.
EDIT: Has xs23_g08o696z9f0mr been synthesized? I haven't found any mentions of the still life.
EDIT: Removed xs23_0ck0fpzc9701226 and xs23_g08o696zdb06jo which have been synthesized by Goldtiger997 below.
EDIT: The remaining three have been synthesized by vilc, making the project complete!

If it is not in the list, assume that it has been synthesised. From Shinjuku with mvr's additions :
