About Herschel-centrism: I'm personally not a fan of it in general, but it's worth noting that Herschels can easily be turned into gliders. Yes, I'm aware that this method is known, but like I said, I wanted to mention it again.

Code: Select all

x = 13, y = 11, rule = B3/S23

There are like a trillion variants on SW-2, this is one that falls in the never used category.

Why is that particular variant never used? It only requires four gliders, it is much quicker than the single beehive, and it doesn't extend as far to the Herschel's left as the two-block variant.

I mean not exactly never, but like, the situations where this would be better than the beehive or two-block or bi-boat don't come up often enough to make a dent in the SW-2 records.

Can you show me the bi-boat version?

Just follow the link to SW-2. Seems to me there have been dozens of variants of Herschel-suppression-after-FNG-is-produced, over the years, discovered and re-discovered. As you can imagine, when all you have to do is cleanly kill a Herschel somehow after it makes its first glider, there are an awful lot of ways to do it.

Here is a Bx106 without the Fx119 output.

There is an edgeshot R at the bottom, but there currently isn't a conduit that could extract it (although a completion of my partial RB34R would change that). Also, keep watching until generation 186 for the latest that I have ever seen something enter the traffic light sequence.

Edit: Is there a way to make this work?

That enters so late that even Pedestrian Life wouldn't be able to stop it. Wow.

Thank you for getting it to work. I tried to make it more compact, and I ended up getting a third glider output (which I highly suspect is already known).

The repeat time is 65 with or without that third output.

Edit: I tried to extract both the Herschel and the glider without luck.

However, the reaction by which two of the catalysts are destroyed gives another eight-cell predecessor for two Herschels without their first natural gliders.

Yep, that's the standard SE7T14 H-to-2G variant of an NW31 edge shooter.

If you want to find out whether an H-to-G is known or not, you can convert it to two-state with Alt+J in Golly, and run the H-to-G classifier script on it. This gets you a nice LifeHistory picture of the H-to-G with all of its glider outputs listed in canonical format.

I've cross-posted the new NW26T157 to the H-to-G thread. That's quite an unusual new discovery! H-to-3Gs are rare in the first place, but Spartan H-to-3Gs (in the old-fashioned sense of "Spartan", even!) are much rarer.

Also, this converter is an NW26 -- an even lane number so now we have an easy Spartan substitution to get whichever glider color we want out of a 2G splitter, without changing the other output:

The odds are fairly good that this will reduce the size of a few guns in the glider gun collection, but I haven't gone looking yet -- quite often these days there already happens to be a very small alternate way to produce all the same periods.

However, there happen to be three other known NW26es already, which might increase the odds that some combination will hit a loop period that was difficult to reach without the NW26T157:

I've cross-posted the new NW26T157 to the H-to-G thread. That's quite an unusual new discovery! H-to-3Gs are rare in the first place, but Spartan H-to-3Gs (in the old-fashioned sense of "Spartan", even!) are much rarer.

We may even be able to get a Spartan H→4G out of it. Looking at the top part, the region that eventually results in the Bx106 output separates from the rest of the chaos without further interaction after generation 63. For comparison, the Herschel doesn't interact with any catalysts besides its first block being eaten until generation 57, and the interaction starting at generation 57 is much too far away to be able to affect the region at the top before it separates. This means that we don't need that particular set of three blocks and two fishhooks at the top; they're merely vestigial remnants of the fact that I found the glider output while trying to get a third output out of AbhpzTa's Bx106_Fx119 Herschel duplicator. There's probably a more compact way to eat that region, but if I remember correctly, there is also a way to turn it into an output glider using a tub and two blocks. I'm sure there is some way to get a glider from that region, considering that it already emits a glider without any catalysts.
Also, I have been considering the possibilities opened by attempting to extract both the Herschel output and the NW26T157 glider. Simply trying to extract both turns the output Herschel's first glider into a blinker.

Code: Select all

x = 30, y = 39, rule = LifeHistory
28.A$19.2A5.3A$19.2A4.A$25.2A3$24.2A$19.2A3.2A$19.2A7$.2A$2.A$2.A.A$3.
2A6$26.2A$3.C22.A.A$3.C.C22.A$3.3C22.2A$5.C7$14.D$13.3D$14.AC$14.2A!

This might be useful for some Herschel-accepting conduit partials where the reaction creates a backwards traveling region that either crashes into the previous conduit or lays down some junk that blocks the next input Herschel, but the blinker will likely cause a problem more often than it solves one. Instead, let's try catalyzing the Herschel with something else at about the same time. Using a block results in some decently edgeshot chaos.

Code: Select all

x = 31, y = 39, rule = LifeHistory
29.A$20.2A5.3A$20.2A4.A$26.2A3$25.2A$.2A17.2A3.2A$.2A17.2A7$2.2A$3.A$
3.A.A$4.2A6$27.2A$4.C22.A.A$4.C.C22.A$4.3C22.2A$6.C7$15.D$14.3D$15.AC
$15.2A!

Unfortunately, the reaction that creates that chaos destroys the block. It may be possible to restore that block with a sparker (until I couldn't find a way to do that) or with a stable catalyst (although that seems unlikely), but let's suppose that we don't want to worry about transparent objects. Can we save the block?
I wasn't able to find a way to catalyze the active region in a way that saved the block before it formed a ∏ (although I only know six catalysts), but I was able to find this:

Code: Select all

x = 31, y = 39, rule = LifeHistory
29.A$.2A17.2A5.3A$.2A17.2A4.A$26.2A3$25.2A$.2A17.2A3.2A$.2A17.2A7$2.2A
$3.A$3.A.A$4.2A6$27.2A$4.C22.A.A$4.C.C22.A$4.3C22.2A$6.C7$15.D$14.3D$
15.AC$15.2A!

The block survives its second catalysis, but the third doesn't work. However, there isn't enough space to place many other catalysts. The only option that even comes close to working is this:

Code: Select all

x = 30, y = 39, rule = LifeHistory
28.A$2A17.2A5.3A$2A17.2A4.A$25.2A3$24.2A$2A17.2A3.2A$2A17.2A5$6.2A$6.
2A$.2A$2.A$2.A.A$3.2A6$26.2A$3.C22.A.A$3.C.C22.A$3.3C22.2A$5.C7$14.D$
13.3D$14.AC$14.2A!

It looks like it's actually going well for a few generations—but then the chaos resurges. I was able to add another catalyst above the ∏ so that the catalysts below failed in a different way (One of the blocks was destroyed, but another block was soon placed to the northeast, and the fishhook wasn't destroyed.), so it's theoretically possible to save the catalysts below the ∏ by placing catalysts above the ∏ without running into the speed of light limit. However, a solution that both saves the catalysts and still allows for an extractable output seems difficult to find in practice. Another idea that I tried was removing the fishhook, but unfortunately, the Herschel's first block does not interfere with the chaos until the catalyst block is already in the process of being destroyed.
Of course, it's possible that catalyzing the Herschel in a different way when it's hit by the NW26T157 glider will yield better results, and I might investigate that after I look for a way to extract a fourth glider without extracting any Herschels.

What if you pipe in that Herschel into a dependent conduit?

The glider still interferes.

I have created a LifeWiki tutorial designed to guide new users interested in making conduits through the process. I figure that the people who are most likely to visit this thread tend are also the people who are most likely to have something to contribute. For example, I think that a section about using search programs to aid in conduit-finding would be appropriate.

Also, I've been trying to get a third output out of Bx106. Here's a near-miss with a century:

The snake must function as a rock, meaning that it cannot lose only cells.

Wasn't there that one interaction where the snake was turned into a block then back into a snake? I'll try to find it again.
EDIT: It was here:

It's here, but it's about as likely to occur as a transparent reaction, so we shouldn't have users trying to find it manually.

Don't worry about it. I was just pointing out an exception.

Here's a B→R.

Code: Select all

x = 21, y = 33, rule = LifeHistory

If one plays it for long enough, one will see a thunderbird sequence.
Also, while I was trying to find a way to eat the region at the bottom, I found an (unfortunately unconnectable) way to turn it into a pi.

Sure, if you want to be completely exhaustive about catalyst placement. There's always a chance. But if you don't want to use heuristics to decide where a catalyst should go or not, then you might as well just break out CatForce and try all of the possible combinations programmatically.

Should I add something like that to the tutorial?

Sure. I still don't know how to use CatForce and I don't understand the documentation, so please it explain it to me.

I don't know much how it works either; that's why I wanted someone who uses and understands it to write the explanation.
