Clean puffer
Let the period of the main engine of a puffer be P. Then a puffer is clean if and only if its overall period is equal to P.

Dirty puffer
A puffer is dirty if and only if its overall period is a multiple of P due to the puffer's exhaust.

[toroidalet]

So this puffer is clean? (run in Golly for at least 100 thousand generations to see the puffer-ness)

Code: Select all

x = 47, y = 24, rule = B2i3/S23-ce5ry6i
3o$o2bo$b3o19$43b3o$43bo2bo$44b3o!

Also, with this example, it's sort of hard to tell where the engine is. Similarly, what would be the engine of a caterpillar, an HBK, or a Gemini?

"Don't like thing.": A joking phrase from the Discord server, to describe the sense that a Life pattern doesn't look like a Life pattern--it contradicts intuition. This is a subjective term, so no pattern is an objective "Don't like thing", but examples may include high-period oscillators and still lifes with unusual cell arrangements.

No, I haven't been able to figure it out. I could make vague guesses that might happen to be right, but there aren't enough specific examples to rule out other possibilities, and no definitions anywhere that I can find.

[Entity Valkyrie 2]

You can find that in my user page.

Magic (in the narrower definition): Combining multiple engines to create spaceships, puffers, rakes or guns.

Magical person: A person who is able to perform Magic.

Corderizing/AbhpzTaing: The activity of combining multiple engines.

Laminar: a descriptor for a wickstretcher (or growing ship or wick ship) stretching a wick with both spatial and temporal period 1 (i.e. one or more line wicks of arbitrary thickness).

Example of a laminar wickstretcher:

Code: Select all

x = 4, y = 4, rule = B2ce3aj/S1e2-cn3a4aqr5i

Paragonal spaceship: a spaceship in a 3D or higher CA with displacement (x,x,x)

Metagonal spaceship: a spaceship in a 4D or higher CA with displacement (x,x,x,x)

[GUYTU6J]

Paragonal spaceship: a spaceship in a 3D or higher CA with displacement (x,x,x)

Metagonal spaceship: a spaceship in a 4D or higher CA with displacement (x,x,x,x)

Then how to call "a spaceship in a 5D or higher CA with displacement (x,x,x,x,x)"? I don't see how the concept of orthogonal (as opposed to diagonal etc) is related to the prefix "ortho-" (as opposed to meta- and para- in arene chemistry).
I would prefer Moosey's suggestion because it is more generalizable:

For a 3D CA on a cubic honeycomb, would a spaceship with displacement (x,x,x) be described as diagonal, or would this apply to (x,x,0)?

I believe that's triagonal.

"Skywriter" - a suggested name for patterns like the one on the top of the Golly page. They can be puffers, guns, or rakes. (Sorry, I don't know how to actually define this)
"Metronome" - a suggested name for periodic patterns with adjustable period. This name might be obscure.

[GUYTU6J]

"Skywriter" - a suggested name for patterns like the one on the top of the Golly page. ...

That's golly-ticker.rle, and therefore no new name invention is needed. Have you been familiar with all of the golly patterns?

"Metronome" - a suggested name for periodic patterns with adjustable period. This name might be obscure.

Like adjustable glider loops or spaceships/rakes with adjustable period?

If we find a smaller snark and/or one with a lower repeat time, it should be called the baby snark (doo doo doo doo doo doo).

Ha. Will the Silver reflector then become "Grandpa Snark"?

Corderizing/AbhpzTaing: The activity of combining multiple engines.

I don't think that it should be called Corderizing because Charles Corderman did not arrange switch engines so that their debris cancels out. Corderships are instead called Corderships because the unstable puffer that serves as their engine was discovered by Charles Corderman. Unless that puffer is the switch engine, the act of arranging multiple copies of a puffer (whether stable or unstable) so that their debris cancels out should be named after the first person to arrange puffer engines so that their debris cancels out, i.e. it should be called Hickerizing, not Corderizing.

I didn't know that! Neat! I just assumed they were called corderships because the uncorderized puffers/rakes would leave behind a trail of objects resembling a cord. And corderships usually involve terminating that 'cord' with more of the same puffer/rake.

a vertical hive looks like a hive

a horizontal hive looks like an egg

the numeral eight represents vertical

8 infinity 8

( and I know that you did not even know that there were two different kinds )

Can you stop nitpicking? It's the convention. Note I said Corderizing, not Cordermanning, that's the act of making a cordership (-like object).

Borrowing from the Rubik's Cube community, we could use the term God's Number to refer to the the number of gliders needed to synthesise any synthesisable still life. In other words the number bounded by 4 ≤ G < 18 from the exhaustive enumeration of all 3G collisions and the RCT.
