### B3/S12 (Flock)

This is a rule that dries up pretty harshly. The ashes left behind from random scribbles generally contain a lot of dominos. A lot.

There is the odd oscillator though, and I've decided to investigate those.

Barberpole-style:

Code: Select all

```
x = 18, y = 5, rule = B3/S12
2o4bo6b2o$o5bobo4bobo$b2o4bo$8b2o5bobo$16b2o!
```

and the "Pickaxe":

Code: Select all

```
x = 5, y = 4, rule = B3/S12
2bo$2bo$obobo$2o2bo!
```

Here are period 4 oscillators that mirror themselves on the third generation:

Code: Select all

```
x = 17, y = 5, rule = B3/S12
14b2o$obo3bobo5bo$o7bo7bo$bo6bo7bo$2b2o3b2o5b2o!
```

A non-mirroring p4:

Code: Select all

```
x = 5, y = 5, rule = B3/S12
b2o$o$bobo$4bo$3b2o!
```

p7, p9 and p14:

Code: Select all

```
x = 33, y = 8, rule = B3/S12
bo2bo$4bo10b2ob2o$o3bo$b3o2bo19bobo3bo$2bo2b3o11bo6bobo3bo$4bo3bo5b2o
2bo10bo$4bo8bob2o$4bo2bo5bobo!
```

If anyone else would like to hunt for more oscillators or spaceships I would appreciate it.

Firstly,

the database has three spaceships that work in this rule, but those are sadly all very big and clumsy.

Secondly, I have just started apgsearching this rule (D4_+2 symmetry, two cores involved), and the results should soon appear

here.

A lot of them are just the ones I know with unneccessary stuff added on, but I did find a few more ones I never discovered before. Thanks!

Shouldn't be way too hard to gun/rake, but you never know. The orthogonal ones are majorly made out of not-so-hard to make polyplets, so all we need to do now is find a genius.

And what exactly is the symmetry? I haven't used any searching tools or anything so I'm kind of a noob to that

apgsearch works by running pseudorandom patterns ("soups") to completion and checking what comes out. I usually ask the program to test symmetric soups, for they usually yield more results. If you want to know what each symmetry is, I can shamelessly self-promote and suggest reading

this.

Changing the topic, posting pictures is generally not a good way to share your patterns. It is much faster and better to do the following:

- Select your entire pattern using
**Edit>Select All** or Ctrl+A if you are on Windows and didn't play much with the settings.
**Edit>Copy** or Ctrl+C.
- Go here and click
**Code** or write [ c o d e ][ / c o d e ] (without spaces).
- Put cursor in the middle and paste.

And finally, my search has found a nice p9:

Code: Select all

I'd say it's unlikely. First, what spaceship would the guns shoot? Even the smallest spaceships in this rule are a bit large. Second, we'd need some kind of sparky medium-high period oscillator to provide sparks which would combine to produce the spaceship, which then has to get out of the way before the next sparks come in.

In normal life (B3/S23) the glider is tiny, only 5 cells, and we have some useful oscillators like the queen bee shuttle, and indeed we have such a gun:

That said, the usual caveat applies here: anyone is welcome to prove me wrong by finding/constructing such a wonderful object.

tldr; probably not.

Well, for a start, this oscillator could prove to be a potential spark donor:
