Can a p4 with one cell period 4 rotor exist?
Not in any two-state rule. If there's only one cell changing, and it can only be either 0 or 1, then there's no way you're getting above a P2. You need at least two changing cells to hold enough information to get to p4.

I interpreted it as 'a p4 with only one cell that oscillates at the full period' (so the other rotor cells are p2).

Here's one with one p4 cell and one p2 cell:

Code: Select all

x = 2, y = 3, rule = B3r4/S0123-r

In general, in a rule with N states, a period P oscillator with M full-period cells cannot exist unless N^M is greater than (EDIT: or equal to) the smallest prime factor of P. A period P oscillator with M rotor cells, however, cannot exist unless N^M is greater than (EDIT: or equal to) P itself, so if your question was whether a p4 oscillator with a single rotor cell (without any p2 support) can exist, the answer is no.

(Correct me if I'm wrong on any of this.)

I actually deleted the post here of mine saying that it is impossible because you cannot simultaneously have a cell born in 3 then die in 3.

He read that, but dvgrn was interpreting it in a different way than what Gustone meant. It's probably possible-- just surround a cell with p2 cells such that it changes its state every other generation and you have a p4 with only one p4 cell in its rotor

JLS reports that no such oscillator exists in B3/S23

@A for awesome: Your example shows that greater than or equal to is the required condition (though not necessarily sufficient as B3/S23 shows)

Edit: Allowing two adjacent p4 cells does lead to oscillators which exist in B3/S23:

Code: Select all

x = 11, y = 11

It's by no means a comprehensive tutorial, but this section of the glider synthesis tutorial on the wiki teaches the basics.

Wow, it seems easy. But it still didn't solve the problem I have:

Unless I've forgotten something, there isn't really an optimized library of these kinds of recipes yet. It would take a custom search to find an LWSS turn recipe with the fewest number of slow gliders.

On the other hand, this is the kind of thing that slsparse can generate for you very easily, as long as you don't mind it being somewhat suboptimal. First pick a G+LWSS with the right orientation that produces a honeyfarm. Then substitute that in to the appropriate stage of a compiled slsparse recipe for a known Blockic (or other) seed for a LWSS at 90 degrees from the initial one:

Code: Select all

There _is_ a known library of single-channel recipes for *WSSes, but those are even less efficient in terms of number of gliders, and they need precise synchronization (but could all be stored in one glider loop, probably except for the initial glider). This one is borrowed from the end of the recipe for Scorbie's Demonoid.

Delete the message and re-post, maybe? I don't know of any other way.

I thought I had figured out at one point that the "last edited by" message isn't displayed to you if you're logged in and you're the one who did the editing. I'm not absolutely sure that that's actually true, and if it is I have no idea why it was implemented that way.

Edit 4-5: Let me turn the sentence to a question.

Wait, can't moderators fix things?
Moderators can fix some things that the forum software is configured to allow them to fix.

Moderators can't magically fix bugs or limitations in the forum software.

At least some moderators (speaking for myself) try to encourage forum users to solve problems on their own, or to take deep breaths and decide that some things maybe aren't really problems that moderators need to spend time on.

If you're unhappy with a "last edited by" message, a reasonable way to solve it would be to edit the message again so that it says "delete me". Then a moderator will probably (but no promises!) come along eventually and delete the message, and the "last edited by" message will go away.

I absolutely agree that it's not very clear why the forum software sometimes displays "last edited by" notes, and sometimes doesn't. Maybe there's a time limit, or a rule that edits aren't recorded until after someone else has replied to a message.

Thank you but how about an example of it in my original question?

Not quite clear what this means. Do you want your original question deleted? I deleted the message that said "delete me", but I think that wasn't the one you're calling the "original question".

It's really helpful if you can be consistent about adding links to posts that you refer to. Otherwise it's surprisingly easy for confusion to set in.

It eats up a fair amount of time to figure out which posts you mean when you say something like "look at my recent posts for the example or even Hunting's post somewhere". If you can't be bothered to spend the time to come up with specific links yourself, there's no particular reason why a moderator should feel obligated to do that work for you.

EDIT: Testing to see if a last-edited-by message appears if someone else has replied to a message.
EDIT2: Testing again, since the message didn't appear due to the above edit. This time putting in some "Reason for editing this post" text.

I can still see the "last edited by" message even though you deleted the "delete me".
That makes me think only the administrator can remove the "last edited by" inconvenience.

The deletion of the "delete me" message removed the last-edited-by note in that message (along with the message). It worked great! I can do the same for the other message if you want -- you just have to edit it to say "delete me", too.

That may not have been what you were looking for, but as I said before, delete-and-repost seems like the only likely way to get rid of a last-edited-by note. Even an administrator would probably have quite a difficult job digging around in the forum database to change the right audit data to make it look like no edits were ever made.

I'm still very puzzled as to why this is even a vaguely interesting thing to worry about. If you don't want the last-edited-by note to appear, don't edit your posts. Right?

EDIT: Here I'm gathering support for my theory that a last-edited-by message doesn't appear if no one else has posted after the message being edited. EDIT2 Looks like that was wrong: the reason last-edited-by messages don't appear in my posts is because I'm a moderator.

Why?

I'm thinking this is the reason.

New theory: message appears automatically if a user edits a post that has been replied to

EXCEPT

if an admin or moderator edits a post, the message only appears if some text explaining the edit is also added. EDIT: Corroboration can be found in experimental edits here. Any counterexamples? If not, I think we have the "why".

Whats the logic or explanation behind the names given to object symmetries?

Also.. What's the general standard for the equivalent of "glide symmetry" in oscillators? For example, the "cis-queen-bee-shuttle." At any single step in its oscillation, it's asymmetric. However, it is composed of two, identical, mirrored halves that are just displaced in time when considering the whole oscillation. Is there simply no distinction, unless its a ship or what?
