What number NRSS is that in this rule? It's really hard to keep track without labelsFWKnightship wrote: August 6th, 2025, 1:30 am

Is there a specific rule which you need to 'defuse'? If so, please post it here.Resu wrote: August 7th, 2025, 3:54 pm How do you make rules less explosive if they are only explosive along an axis?
There are some better examples, but here is one:

Not really. Any (X)MO(Y) (SMOS, OMOS, etc...) has to have subparts of an X which behave like a Y. So, in this case, the p27 oscillator is not made of p34 oscillators, because each of the four quadrants doesn't reappear in 34 generations. If you have to split the parts of X apart to make them behave like a Y, it's not a (X)MO(Y). Otherwise, there isn't a way of separating non-trivial patterns from trivial examples like this "Still Life Made Of Spaceships":Resu wrote: August 11th, 2025, 9:43 am Is this an p27 OMOO(oscillator made of oscillators)?

Well, the boring answer is because people in the past defined it as such. For example, what I'd call a trivial SMOS is one which doesn't satisfy the strict definition of a SMOS as described on the wiki:Resu wrote: August 11th, 2025, 11:08 am Why is it considered trivial?

The more personal answer is that if the sub patterns never actually moves like a spaceship, I don't think the entire pattern is a spaceship made of spaceships. It's just a spaceship whose parts resemble other spaceships.SMOS Wiki Page wrote: A stricter definition of SMOS requires the spaceships used in the SMOS to be allowed to go through 1 full oscillation cycle before interacting with the other.

I meant cells. That stupid swipe typing!
Billions, if not trillions, as just B34a/S23 is explosive, and you can add as many transitions as you want.b-engine wrote: August 12th, 2025, 12:28 am Out of all isotropic rules with B3ai and no B01ce2ace, how many rules are explosive (by running 100 soups and see if anything touching the 5000*5000 border is larger than 100 cells), how many rules are stable (nothing touching the border)?

No, but I think "Flying Dutchman" (pl. Flying Dutchmen - this would refer to the whole set and not solely to any individual (5,2)c/190 ship or period-multiplied ship) has some precedence on the forums if it/the general (5,2)c/190 set were to be named.ThePlayzr wrote: August 19th, 2025, 2:33 am Does the oblique spaceship have a name?Code: Select all

Give it all of s012-in3ajr4a, then the trailing end of a spaceship cannot die. For a specific rule, post it, and there may be proof. (eg. b1e2a/s cannot have spaceships)b-engine wrote: August 19th, 2025, 6:29 pm How to prove that an isotropic rule with B2a, B2ce or B3ai has no spaceships?
There's the "Spaceships in Life-like cellular automata" project. You might need Cygwin for it, though. You'll also need Python to use the new-gliders.py script (which tells you which speeds are known and which aren't).poolperson87 wrote: August 20th, 2025, 1:27 pm Are there any "CA projects" I could contribute to?
I don't have WSL or apgsearch by the way.
