I do want to point out that this is not the first hassler of this region. Previously known p116 below. I'm not sure why this region is so far down in census.rle (#206); octo3obj places it roughly 15th.

I still use code tags regularly for patterns. It would also break everything before maybe 2022 or so (not sure of the exact year), since the pattern tag is fairly recent.

That is already included:

(or B-heptaplet, if the top-left cell is shifted one cell left)

This pattern often arises with the cell at top left shifted one space to the left, producing a seven-bit polyplet that shares the same eight-bit descendant but is not technically a heptomino at all. Many ...

I want to point out that the above post may be one of those 1-post spambots. If it turns out to be, I will delete both that post and this one.

To Zach Cunningham: a second post by you, regardless of content, proves you're human. Our one-post spambots follow a very specific pattern.

My first thought was StateInvestigator, but it doesn't quite match. Here is the labeled p19 with a StateInvestigator state 4 cell. It's a valid oscillator, but it's p8. I believe the difference is that the glitched cell can turn on and count as two while it's on, while the state 4 cell always counts ...

What title should this new p11 domino sparker have? I moved p11 domino sparker to p11 delayed domino sparker because the former title is now ambiguous. The former currently redirects to the latter, but I'll turn it into a disambiguation page once a page on the new p11 is created. Note that despite ...

I downloaded jslife, but I don't know how to open .lif files. Can someone help?

You can open .lif files directly in Golly.


I also just downloaded jslife and have Golly, but I can't seem to open the .lif files in Golly. Maybe it's because I'm using a phone. How would I import all the files ...

That only has an average density of 5/12.

That joins the pi-heptomino sequence after a few generations.

These are good things to hear, but you two might be in the wrong thread. This thread is specifically for requests to be able to edit LifeWiki. You might want the Introductions thread https://conwaylife.com/forums/viewtopic.php?t=530

Which match the rule 30

Hello and welcome to the forums!
I think you need to be a bit more descriptive, I have no idea what you are talking about :oops:
I would recommend looking at Isotropic non-totalistic rule for how to make isotropic rules, as they are a good place to start on CGoL.

The first code block is equivalent to this:

Is it possible for pseudo still life components to be connected orthogonaly?

It seems that all definitions of strict still life assume by default that islands (polyplets) are indivisible - is there a proof for that?


It is possible.
