Each is off by two cells, one creates a beehive. 4c/11 puffer maybe?

Sorry, but it is not a puffer. A puffer must go infinitely and leave infinite trail.

I have to say that is cool, and while it is not a puffer as one user mentioned, it definately deserves to be investigated further. Because as you said, it is only a couple cells off and these cells are behind the head so it should be possible to have the pattern interact with another object and not completely lose its forward motion

New Pi Velocities
I know about the 9c/30 and 17c/45 pi reactions, but I have never seen any mention of these

1. Pi advances 10 cells in 24 generations, (5c/12)

Code: Select all

x = 5, y = 12, rule = B3/S23
2ob2o$b3o$2bo9$b3o!

2.
Pi advances 13 cells after 31 generations (13c/31)

Code: Select all

x = 5, y = 14, rule = B3/S23
2ob2o$o3bo$b3o11$b3o!

3.
A less ideal but still potentially useful reaction where the pi advances 13 cells after 36 generations (13c/36). The issue here is the blocks that are formed behind the pi, but it may still be possible to work around them

Code: Select all

x = 5, y = 16, rule = B3/S23
2ob2o$o3bo$b3o11$2bo$2bo$2bo!

3A.
A part of the previos pattern where the pi advances 4 cells in 6 generations,(2c/3). That's probably too fast to be of much use, but still worth including just in case.

Code: Select all

x = 5, y = 6, rule = B3/S23

2ob2o$b3o$2bo12$2bo$2bo$2bo!

4A.
A sub-part of the prior pattern which advances 5 cells in 7 generations (5c/7). Again, probably not useful since it is much faster then c/2, but I still feel like including it just in case

I like how the pi dies and is then essentially brought back to life by the debris that destroyed it. The pi's reappearance from it's own ashes was an accidental discovery.

If anyone can find a reaction to turn the beehives back into hats or speed up the pi to 14c/40 (3c/8) that would be great.

Was messing around on the ipod app I talked about on my previous post and found a smallish p2 oscillator. (does not require any array size; it's finite.)
. = dead, * = alive

....**....
...*..*...
...*.**...
.**..*.**.
*.....**.*
*.**.....*
.**.*..**.
...**.*...
...*..*...

I have a feeling this has been discovered already, but if it is, I've never seen it. Basically I ended up with it by inserting live cells into the evolution of the fleet predecessor that looks like a too-small *WSS.

I was looking through some old notes and found this fairly nice pi-to-R converter:

What's odd is that I can't remember ever posting this pattern, or even seeing it (the file creation date indicates that it was found over two years ago). Here is a full Herschel conduit based on the converter:

Was messing around on the ipod app I talked about on my previous post and found a smallish p2 oscillator.

I actual had found the same oscillator, and I think using the same app. I added two points to a bakery:

I recently found a better app, called Life Explorer, which I think is better. It has a MUCH larger world (300,000 cells), has many pre-downloaded patterns, and you can save almost as many as you want. Also, you can edit the shape and color of the grid and squares, which is a little aesthetic bonus. The only downside is that the algorithm is fairly slow, and there is a moment of lag if you edit it and then run it.

Two gliders shifting a blinker by three diagonally.

Along the same general lines, with the right relative timing two diametrically opposed gliders can move a block by one cell, a loaf by two cells, or a blinker by four cells diagonally.

Though the alternation is hard (or impossible) to do, the reaction can, in fact, be turned into a glider-based puffer (though this puffer may be too big). Alter the phases of glider streams to alter the output. This is the dirtiest variant (cleanest is a block-layer).

Howdy All-

First post. I just got Life, known next to nothing about it, and am totally ignorant of all the prior discoveries. So while I did "discover" the following, as in it emerged accidentally while I was tinkering around, I'm sure somebody else did it long before. Still, it's pretty cool so I thought I'd mention it.

I was experimenting with Schick Engines to see what sorts effects I could make by adding other spaceships to influence the exhaust stream. After making a bunch of horrifically dirty puffers and rakes, I came up with a twin forward rake that leaves a nice, clean trail of block pairs from the get-go, with no pre-loaded exhaust needed.

Code: Select all

#CXRLE Pos=0,-32
x = 27, y = 21, rule = B3/S23
22b2o$10b6o5b2ob3o$10bo5bo5b5o$10bo12b3o$11bo$bo$o$o3bo$4o9b2o$6b3o5b
2o$6b2ob2o6b3o$6b3o5b2o$4o9b2o$o3bo$o$bo$11bo$10bo12b3o$10bo5bo5b5o$
10b6o5b2ob3o$22b2o!

Somehow, the exhaust-molding spaceships set up resonance in the exhaust plume somewhat like in a typical glider gun, but this collapses into 1-shot guns that leave 1 block behind. As these 1-shot guns coalesce out of the exhaust plume, 1 of the steps looks like the letter J, so I call them J-Guns, although they probably already have an official name I don't know. They have to be arranged in pairs as left by the rake here, otherwise they quickly go to nothing. The whole sequence of what happens to the exhaust looks pretty cool as it plays out, so I'm happy.

Thanks for looking.

[DivusIulius]

Howdy All-

First post.

Welcome! That's a superb pattern!

[Bullethead]

Welcome! That's a superb pattern!

Thanks on both counts. New guy buys the drinks I suppose, so what'll everybody have?

Do this pattern and/or the "J-Guns" have names? Surely I'm not the 1st to ever see it and I'd like to use the generally accepted names.

Continuing to tinker with this basic idea, I came up with a totally clean back rake that leaves nothing behind at all except gliders. It's like opening a zipper except there's no track ahead. Certainly this has a name, too. Anyway, because it leaves no wake, something else can follow along behind, provided it's narrow enough to fit between the glider streams.

Code: Select all

#CXRLE Pos=0,-2
x = 36, y = 25, rule = B3/S23
32b3o$31b5o$22b2o6b2ob3o$10b6o5b2ob3o4b2o$10bo5bo5b5o$10bo12b3o$11bo$b

10bo12b3o$10bo5bo5b5o$10b6o5b2ob3o4b2o$22b2o6b2ob3o$31b5o$32b3o!

In the forward rake 2 posts above, the 1st gliders appear at g119 and thereafter emit at p72. In the back rake here, the 1st ones appear at g97 and thereafter are p24. Thus, these rakes and be used together to create regularly timed glider collisions and regularly interrupted back streams. So now I'm tinkering with such interactions.

[dvgrn]

Do this pattern and/or the "J-Guns" have names? Surely I'm not the 1st to ever see it and I'd like to use the generally accepted names.

There's no standard name that I know of -- I had a quick look at Paul Tooke's and Jason Summers' collections of c/2 rakes and puffers -- "ptpuffer" and "jslife/c2extended" -- but didn't see that particular dirty p72 bilateral forward rake.

Looking again at how many different puffer and rake periods have been constructed (the above collections are worth a look!) I can see how people might have run out of names before this one showed up -- there are an awful lot of bilaterally symmetrical puffers of various periods.

My understanding is that if you're building bigger patterns it's generally easier to work with a rake that has just a single output instead of two mirror-image ones. You could certainly block off one of the two outputs of your p24 rake, but then there are very small and well-known alternatives in the competition -- see for example the p24 backrake in Dean Hickerson's broken-lines pattern (Golly's Patterns/Hashlife/broken-lines.mc). Even that is just called "a p24 rake", I think; only a few early ones like the "space rake" (p20) got more specific names.

I want only eater, But It seems hard.

So, Can you get only Eater from this reaction?

In response to above, this ain't pretty, but it works:

Code: Select all

x = 204, y = 48, rule = LifeHistory

If the boxed LWSS is removed, a glider can escape to do more things.

Here's a more compact cleanup (3×LWSS+HWSS, take s31 ticks after the eater's formation)

Code: Select all

x = 60, y = 22, rule = LifeHistory
