### A thread for some REALLY small spaceships

This is just for fun

Also, all my works is done *manually*. Which means, definitely without any computer program(expect Golly).

Rules:

1. Only for 2-state range-1 non-B0 isotropic Moore neighbourhood rule.

2. Ships cannot require B2a.

Current tasks:

1. For bo$obo! p3 c/3 spaceship.

Removed tasks:

1. For p2 c/2 spaceship fit in a 3x3 bounding box(in the smallest phase).

Not possible. Everything in small BBs is already thoroughly searched.

Oh, I thought this was for GOL.

Considering there are only 512 patterns in a 9-cell bounding box (including rotated versions), I just assumed he wasn't talking about Life.

What's more impressive is the standard glider, which does lie entirely within a 3-by-3 bounding box and is c/4 diagonal.

[Edited to correct number, replacing 1,024 (2^10) with 512 (2^9).]

That's why I said that they were not possible.

The c/6 diagonal spaceship from Just Friends also fits in a 3x3 box (a 2x3 box, in fact) in all of its phases.

Code: Select all

```
x = 2, y = 3, rule = B2-a/S12
o$bo$bo!

Digging up old post, but other ships except Gamedziner's one:

Code: Select all

```

Almost certainly.

Though what I want to see is a MAP rule with a 2-cell spaceship that behaves unusually— it just turns into a mess and then forms again.

Oops. I think I need to add one morr rule:

**Isotropic Non-totalistic only.**
EDIT: More bo$obo! ships

Code: Select all

```
x = 3, y = 2, rule = B2ce3ei/S2ac
bo$obo!
```

Code: Select all

```
x = 3, y = 2, rule = B2ce3e/S1c2a
bo$obo!
```

That's all c/2o bo$obo! ships possible, including Gamedziner's and my ship in the previous post.

EDIT: Not fits in 3x3 box, but accidentally and really small(3 cells):

Code: Select all

```
x = 5, y = 2, rule = B2ek3aei/S02c
o3bo$2bo!
```

EDIT: This line is impossible:

Code: Select all

Whoa! This is really impressive!

Also, failed try for a c/3 bo$obo! ship makes this:

Code: Select all

```
x = 3, y = 2, rule = B2e3aein/S02c3i
bo$obo!
```

It's a c/3 wickstrecher sending signals traveling on the wick it streches.

(When I did this I was manually brute-force searching for that previous-posted impossible line. Almost, one extra cell which is weakly connecting to the ship.)

Hexagonal Generations spaceship that resembles bo$obo! (took me so much time to get this):

Code: Select all

```
x = 11, y = 11, rule = 0/2/3H
2A2.2A$A5.A3$A8.A$A9.A$.A8.A3$4.A5.A$5.2A2.2A!

2A2.2A$A5.A3$A8.A$A9.A$.A8.A3$4.A5.A$5.2A2.2A!

(These fit in a bounding hexagon with side length less than or equal to 3)

EDIT: I just realized that you can't use non 2-state rules. UUUUUUUUUUUUUUGHHHHHHHHHHHH WHY CAN'T I EVER FIND A NICE HEX RULE

*is* correct: patterns with single cells on a 2x2 grid in that rule simulate

Margolus rule 15, thanks to the combination of B2c, B2n, B3c and B4c, and the absence of B2i or S0 (the only transitions that can break Margolus-based oscillators with these tiles).
