Yes, although it's more commonly comes from one of these two forms:

Code: Select all

``````x = 18, y = 5, rule = B3/S23

There's even a grate in the natural evolution of the Herschel, although it soon gets disturbed.

Is it possible to clean up the debris around the still life created at gen 145 in 4 gliders?

Code: Select all

``````x = 54, y = 46, rule = B3/S23

Alternatively, if the bottom of this reaction can be synthesized in less than 9 gliders, it would be an improvement as well:

All still-lifes with populations up to 32 bits have already been found. By repeated applications of simple converters, around 97% of the ones up to 24 bits (at least) can be synthesized, and it's likely that one wlil find similar statistics for larger ones.

``[messy paperclip synthesis]``
Catagolue, or the LifeWiki will tell you you can build a paperclip with three gliders. If you don't know it's called a "paperclip", use Mark Niemiec's search page. Paste in RLE copied from Golly

Code: Select all

``````x = 5, y = 6, rule = B3/S23
2b2o\$bo2bo\$bob2o\$2obo\$o2bo\$b2o!``````

### Re: Still Life Synthesis Thread

After some fruitless searches, I found this. Since the Big S can be synthesized in 3 Gs, though, I don't have high hopes.

Code: Select all

``````x = 15, y = 8, rule = B3/S23

EDIT: Another not-so-useful synthesis:

Code: Select all

``````x = 13, y = 3, rule = B3/S23

Wow. Wasn't sure we were going to see a recipe for that any time soon. Seems like if that mini-Borg SL is buildable, the next group of still lifes (the 19-bitters) doesn't stand a chance.

That doesn't say so much about the 17-bit and 18-bit still lifes being constructible at less than one glider per bit, though -- this recipe needs 83 gliders to make a 35-bit still life.

Here's the continuous synthesis, produced by the usual process of being mystified about why chris_c's script isn't working, and then finding another place where the spacing wasn't consistent, and fixing it, and being annoyed that the script still doesn't work, and then finally finding the very last off-by-one problem and getting a good result.

Someone should really patch up that script so that it does auto-alignment between stages, or at least some level of alignment verification, instead of just assuming everything is perfect.

### Re: Still Life Synthesis Thread

Just found this xs30 and the soup doesn't look extremely promising but there might be something useful because it separates very cleanly into a small pattern that evolves to the still life.

Based on a soup from Catagolue and in desperate need of improved cleanup, currently at 11 gliders:
