I have two questions this time:
1) I don't understand the Larger Than Life rule notation. Quoting the wiki:
Ssmin..smax specifies the count limits for a state 1 cell to survive. Bbmin..bmax specifies the count limits for a dead cell to become a birth.
What are count limits? Also, I can't seem to transfer LTL rules from the forums or Catalogue to Golly sometimes. The notation is slightly different and I don't know how to convert them.
2) I'm not sure if this is the correct thread to ask this but how do I bump a topic? I know it's in the FAQ:
By clicking the “Bump topic” link when you are viewing it, you can “bump” the topic to the top of the forum on the first page.
I don't see a link like that.

By "count limits", what's meant is the range of numbers of neighbors that a cell can have within its neighborhood to either be born or survive. For example,
Bugs has the rulestring R5,C0,M1,S34..58,B34..45,NM - indicating that within a range-5 Moore neighborhood, cells must have between 34 and 58 (inclusive) living neighbors to survive, and between 34 and 45 living neighbors to be born.

What if I want a discontinuous range of numbers?

Thanks! Though is it possible to exclude certain conditions like, just as an example, 32...43 excluding 35 and 40? Also, how do you run a rulestring like this in Golly:
The rule is Marine.

The FAQ mentions all kinds of "optional options" for phpBB, that aren't enabled in this particular instance -- "The team" link, usergroups, etc.
To bump a topic, you post a new message to the thread. But please do this very sparingly, preferably when you actually have something new to say on the topic.

Yes, I didn't want to post anything because I didn't have anything relevant to say. So there's no other way?

Is there possibility for a ‘transparent glider reflector’ for a single glider?

Sure, if I'm understanding the question right. One of the best hopes for improvement in self-constructing circuitry would be if someone can turn up a set of scattered common still lifes that all happen to return to their previous positions after being hit by a glider -- like the
sidesnagger, but also emitting one or (much preferable) two gliders.
The still lifes could all be transparent, in which case you could build strictly volatile oscillators at whatever period the reaction's recovery time supports. But it would still be almost as big a discovery if some still lifes acted as standard catalysts.
This is a reachable search space, where everything beyond the reach of
sngdetect, and more recently CatForce, is pretty much unexplored. The odds of success don't seem too terribly high, but there
could be a pattern of half a dozen blocks or something that regenerates itself perfectly and puts out a glider.
The search task is highly parallelizable. For example, it would be easy to divide an enumeration of all constellations inside a 16x16 box into manageable-sized chunks, and keep sending the next chunk out to customized apgsearch instances. Just doing this as a custom symmetry and reporting to the current Catagolue would turn up some new stuff occasionally, so that might be enough to get people to keep contributing even if the Spartan-stable-reflector part of the search didn't turn up anything for months or years, as it probably wouldn't.
But we'd need some changes to apgsearch so that it could recognize a stable reflector when it saw one, and to deal with the enumeration details so that the distributed search could maybe eventually be exhaustive instead of just random incomplete coverage of the search space.

What is a "maximum v loop", exactly?
We do have the technology to build a stable reflector that rebuilds itself completely while reflecting a glider, I suppose. Seems like a lot of work for literally no effect, though.

I'm guessing that he means strictly volatile loops, in which case, the PD-pair reflector and the thunderbird hassler-supported bumper won't do.

How do we know exactly that the minimum population size for infinite growth is 10 cells? Can't we just make a block (which can be trivially made smaller into a pre-block) interact with an r-pentomino to create a block-laying or glider-producing switch engine? Has this been tried before? For example, in switch engine ping-pong, a glider collides with the debris of an r-pentomino and makes a glider-producing switch engine.

Good question. The answer is that
Nick Gotts tried every combination of this form.

Which post says this exactly? Also, There's not only the pre-block but also the t-tetromino, which evolves into a traffic light, and the pre-pond. It feels like there are way too many patterns to check.
Edit: I found it, but I still have trouble understanding it. It seems to me that they're focusing more on clusters, though what I'm asking is about two different clusters.

This one and the one below it. You're talking about what he calls 'two-cluster' patterns. There are a lot of them, but not too many to check.

No, there's no predecessor that can turn on that dot without interacting with the rest of the pattern.

But you can insert a domino while interacting with the pattern in a way that still allows the MWSS to be created.
