Is there an isotropic two-state rule with at least five distinct common slopes? It would be better if the spaceships each fit in a "5 by 5" bounding box.

I am very sorry. I forgot to mention LifeViewer support.

[635318657]

A 2-state INT rule that has 6 spaceships with distinct speeds, each fitting within a 3x3 bounding box:

Code: Select all

x = 68, y = 3, rule = B2e3-ckqy4rz5r/S2-n3eijry5i6a
14bo25b2o10bo12b2o$3o10b3o10b3o10bobo10b2o11b2o$obo10bobo11bo13bo11b2o
10b3o!

The speeds are c/2o, 2c/5o, c/4o, c/4d, c/7d, and c/8d. The c/4d is a fake glider.

Can someone find a 2-state INT rule with 7 or more spaceships with distinct speeds, each fitting within a 3x3 bounding box?

My rule request:

• INT
• Not explosive
• Soups will form into stable blobs with lots of line structures on the inside
• Chaotic regions propagate throughout the blob, shuffling the structures around
• When active regions reach the edge of the blob, it causes the blob to grow in that direction
• Activity dies down eventually to prevent the rule from being explosive

I was thinking of a rule with organic blobs with about 50% density and solid lines. Additionally, I want spaceships to be possible in the rule.

Uh, no. That rule doesn't have spaceships. Additionally, the blobs have to move around.

Is it possible to create a rule similar to this:

Code: Select all

x = 3, y = 7, rule = LifeNoted
.A$3A2$.A2$3A$.A!

except, instead of cells that died being assigned different colours depending on their neighbour count, they also took the neighbour arrangement into consideration, so that for example 1c and 1e deaths appear different?

It is certainly possible, but it would require lots of different cell states.

That isn’t possible.
Firstly, in your examples, the glider is both an oscillator and spaceship.
Secondly, B3678/S23 can’t have the HighLife rep.

This rule (B2n3acein4eiknqtw/S02aen3aikr4aeijwy5iy6cn) provides a stable 180 dot reflector for T. Nothing very noticable apart from that, as construction is not rich at all in this specific variation. The reflect reaction has a great rule range though.

If we golf a small ship which 'passes through' when hitting each other on the head, and make a splitter with 0 (same) and 180 (opposite) emitting directions, we would only need 2 such splitters on the same x or y-axis! In the dot case this is pretty common, as you can run a soup and often see a T bouncing between 2 dots in the rule above.
...

Cross-thread post for this rule to be improved or regolfed. You may check the thread this post is from first to understand the context, so that the rule expectation is clearer. A great thanks to anyone attempting this!

A 3-state rule with a (4,3)c/10 spaceship and a c/2o spaceship

Why do it have to be three stated?
Do it have to be INT or OT or some other choice?
There exist plenty of 2 stated rules with these properties, I’ll look for them using EPE when I can use the computer I have it on.
