That would be xq0_2702072

[Moosey]

That would be xq0_2702072

That implies that it's a period 0 spaceship (whatever that would be)--as it turns out, x0_2702072 is a perfectly valid apgcode

[Macbi]

That would be xq0_2702072

That implies that it's a period 0 spaceship (whatever that would be)--as it turns out, x0_2702072 is a perfectly valid apgcode

A period 0 spaceship is a pattern that returns to its original state (up to a translation) whenever the generation number is a multiple of 0. So the agpcode is correct. (But I suspect apg will deny this, because his irrational fear of the empty set probably also extends to the number 0.)

It should be xp0, rather than xq0, though -- after 0 generations, it remains in the same place.

An oscillator is by definition a spaceship with translation (0, 0). (Although perhaps a spaceship can't have zero translation)

Is there an official name for this spark?

Code: Select all

x = 3, y = 4, rule = b3/s23
bo$3o$3o$bo!

This is a phi spark.

Not quite. Notice the definitive phi-shaped phase never shows up.

In a phi spark, the terminal three-bit V sparks end up with four blank rows between them, instead of six blank rows as in this case.

It's a "worker bee core" then.

Is it possible to make a spaceship based on Lumps of Muck?
Maybe something like a fuse for the blocks that produces the gliders needed to sustain the reaction in bricklayer?

Is it possible to make a spaceship based on Lumps of Muck?
Maybe something like a fuse for the blocks that produces the gliders needed to sustain the reaction in bricklayer?

Nothing is impossible. Well, lots of things are impossible, but this isn't one of them. On the other hand, it would be hard to know where to start looking for a clean fuse reaction that burns at precisely 5c/174 and produces exactly the right gliders.

It would probably be easier to invent some new diagonal Caterloopillar technology, set it up to run at 5c/174, and put together some edge-shooting rakes at that speed. You could support a moving LOM in a spaceship that way, without having to figure out how to put multiple LOMs together to get an over-unity reaction.

How does one extend the period of weekender distaff

[dvgrn]

How does one extend the period of weekender distaff

Is this answer from codeholic what you're looking for?

The pattern comments say

Code: Select all

#C Many but not all periods of the form (16982+224*n)/q are possible.
#C http://www.conwaylife.com/forums/viewtopic.php?p=12047#p12047

-- "many but not all" because you can't always put q signals in the loop. Occasionally a northbound LWSS signal will happen to get in the way of one of the SEward slow-salvo construction gliders that incrementally builds a seed for the next LWSS.

[/url]Holzwart proved in 2006 that 2c/3 is the maximum speed at which signals can move non-destructively against the grain through zebra stripes agar.

Does this mean that there could be non-relativistic negative SSes?

Does this mean that there could be non-relativistic negative SSes?

Spaceships slower than any chosen speed can be proven to exist for some non-vacuum agars -- e.g., sufficiently sparse scatterings of blocks -- and even for some agars where it's possible to follow an unbroken Moore-neighborhood chain of ON cells for any chosen distance in any direction, like a version of this with some huge unit of repetition:

If your question is specifically about the zebra-stripes agar, I _think_ that's an open question, but I'm not sure. I don't believe there are any known results that are particularly promising for arbitrarily slow against-the-grain negative spaceships in zebra stripes.

[Moosey]

If your question is specifically about the zebra-stripes agar,

It is.

I _think_ that's an open question, but I'm not sure. I don't believe there are any known results that are particularly promising for arbitrarily slow against-the-grain negative spaceships in zebra stripes.

Nor are there any for arbitrarily slow elementary SSes in the vacuum agar.

Are there any, say, c/2 or c/3 against-the-grain zebra stripes frontends? Preferably promising ones? If there are...
c/2 ships with bubbles will happen soon.

[testitemqlstudop]

[/url]Holzwart proved in 2006 that 2c/3 is the maximum speed at which signals can move non-destructively against the grain through zebra stripes agar.

I actually think 2c/3 IS the maximum speed a signal can move, destructively or not.

[Moosey]

How feasible would it be to construct a colony of "small" UCCs that would repair itself?
Presumably it would be difficult, since the vacuum agar is generally harder to permeate chaotically than most areas with stuff in them

I have a script that compiles the full set of p14-p1014 guns, based on chris_c's current README -- which is a bit behind the times these days. Not sure if that will change any time soon; chris_c seems to be busy these days. But I don't see anything in the gun thread about 68P32.1. (?)

You could certainly get a p160 by period-doubling the fixed p80 using a 68P32.1, but it looks like that would end up quite a bit bigger than the one based on the p448_4.

Here's the p80 gun in the collection, based on the small p20 gun:

Where does the rumor come from of a p160 gun using 68P32.1?

From these two edits by Entity Valkyrie:
https://www.conwaylife.com/w/index.php? ... ldid=50854
https://www.conwaylife.com/w/index.php? ... ldid=63475

I was mainly asking so that I could add a LifeViewer demonstrating this, since it's not very helpful to state that it can be used as a filter without showing how and it's not exactly obvious just by looking at it.

For now, I've added a {{citation needed}} tag to both of these pages, and added a message to his talk page asking about it.

I'm making a sort of game for APKNite in Python that involves guessing which of 2 starting patterns will reach the highest generation in John Conway's Game of Life. And to do this, I need some different patterns to start with, but I can't come up with any ones that would be interesting. Any ideas for starting patterns?

I need some different patterns to start with, but I can't come up with any ones that would be interesting. Any ideas for starting patterns?

How about random selection from the available pentaplets, hexaplets, or heptaplets? Or possibly randomly chosen short words in some particular Life font? There are other more readable options, like the font Eric Angelini used to try to find self-referential sentences. Here's a sample by Dean Hickerson from June 2017:

I'm astonished by the tubs this quadratic replicator produces (and also the history envelope). Does this fractal appear elsewhere?
