Would it be possible to make an RRO puffer such that the RROs "interlink" like the following?

Code: Select all

x = 136, y = 20, rule = B2-an3-eiky4aiqw5ijnr6ak/S012ik3-acir4kqw5acq6ack7c8
bo15bo15bo15bo15bo15bo15bo15bo15bo$o15bo15bo15bo15bo15bo15bo15bo15bo2$

That thing is kookier than chris cain's camelship and given that it literally has gliders bouncing around inside there must be a gun.

Have you maybe tried looking for something along the lines of a 1/2/4/8/16 RRO? Or a 1/2/3/4/6/8/12/16 RRO? These might be easier targets than 1/2/3/4/5/6/7 for now.

I am not looking for a 1/2/3/4/5/6/7 - that's far beyond what we can find. I am looking for any 1/x1/.../xn/7 (e.g. 1/2/4/5/7, or maybe 1/2/3/4/6/7). I suspect that it will be much easier to find a 1/x1/.../xn/16 as the RRO must move quite fast for the 1/2/4/8 we have the 'ships' get already quite close to each other, for a 1/x1/.../xn/16 we require roughly the double radius.

This is really neat. The constellation of dots actually remains intact (Although a few more dots are added) and it produces 3 additional gliders, although I don't really see how the 2 that go behind the 3 glider group can be used directly, and the 3 glider group does change phase.

This could possibly lead to a spaceship.

Unless it has a really tight orbit.
Yes, but finding a p840 RRO is more tricky than it looks like, and it is the smallest possible period, for 1/2/.../7 'only' 420 we be required, in a standard design one 1 quarter would have a period of 105 which is quite high.

Yes,adding B5q makes it more stable

x = 18, y = 13, rule = B2-an3aj4ar5aciq8/S01c2-en3ejkn4j5aqry6k7e

still occasionally something like this might happen:

Does anyone in this thread know of an RRO that could be simulated by metacells in order to produce an RRO in Life, like I described in this post?

A single metacell has to circulate? But you'll have pairs or quadruplets of metacells circulating in separate loops to make the RRO?

It doesn't seem as if the multiple RRO loops really need to overlap. You still get the same effect of a rotated copy of the original pattern when the loops are completely separate from each other:

Hope I got the diagram right -- it's a little confusing... After a LifeWiki edit I made a while back, calcyman worked out this same method and summarized it in an email:
In November 2018, calcyman wrote:A single copy of the oscillator will look like this when zoomed out:

$b2o38b2o$bo39bo2$bobo37bobo$bobo37bobo!
and when you zoom in, you see that the four connected components each have their metacells pointing in different cardinal directions.

This is just as loopable as the original RRO, and has mod = period/4.

If you don't like the fact that each copy of the oscillator is disconnected, then you can fudge it by having a (non-meta!) glider circulating between the copies. Specifically, as the metacell self-destructs, you can take advantage of a diagonal domino to reflect a glider by 90 degrees:

These meta-RROs still aren't _quite_ the same as regular RROs, since the circulation is happening in multiple separate loops instead of all in the same loop; there doesn't seem to be any way around that.

With the four loops completely separated as shown above, it should be easy to program a single eight-state 0E0P metacell to travel in an eight-step square, or even just to travel in the tightest possible square using only four states. Is that what you're looking for, or am I missing the point of the question?

Yes,adding B5q makes it more stable

These rules are not explosive in the typical sense, but rather are part of a class of rules which can explode but the pattern acquires odd symmetry, with the explosion being caused by continuous activity along the line of symmetry (I suppose there could be rules where this happens with even symmetry, but I've never seen any); these rules are usually apgsearchable as usual for C1. Wild Seas is another example of a rule with such behaviour.

Good point! That certainly makes it easier.

Is that what you're looking for, or am I missing the point of the question?
An eight step square like this:

Code: Select all

x = 23, y = 23, rule = B/S012345678

won't work. For one thing we only have seven live states, the eighth state is the vacuum. But also I want two copies to be able to orbit each other without interacting. Unfortunately if the two copies come within one cell of each other then when metafied the two copies will interact. So the unoccupied area in the centre of the RRO needs to be larger than a single cell.
