As written, this looks like a conduit that changes empty space into a herschel and a century, which would indeed be truly remarkable. I assume that the herschel should be green. When you post, it is usually a good idea to hit "preview" first instead of "submit" to make sure the post is as intended. Embedded patterns (even in LifeHistory now) should be run in the LifeViewer, to make sure they perform as expected. I have frequently found typos or pattern errors in my posts this way.

That format is, in fact, used in the Elementary Conduits Collection, so there's nothing inherently wrong with it; it just makes it slightly harder for other users to see whether it works. By the way, white or possibly yellow are also acceptable colors.

Yes, if all the inputs were green/white/yellow in the ECC, you couldn't reliably run the stamp collection pattern -- stray outputs would be flying all over the place. So there you generally just change the one input you're interested in.

When there's just one pattern being quoted on the forums, if it's supposed to be runnable, it's really nice if it's in a form that LifeViewer can run. It definitely increases the audience: relatively few people will bother to copy the pattern out into Golly to see exactly what it does.

In this case, the pattern does indeed convert a Herschel into a century. However, the "output" century is completely surrounded by still lifes, and within ten ticks it crashes into two of those catalysts, without ever going outside of its previous reaction envelope. So it's impossible to add any further catalysts, which makes it pretty definitely a dead end.

So sad. We will never get that century out. :S

Anyway I found this common stairstep predecessor:

Code: Select all

x = 3, y = 5, rule = LifeHistory
2.E$3E$2E2$E.E!
I should've find something interesting next.

An eater4 can eat half of a traffic light:

Code: Select all

x = 14, y = 14, rule = LifeHistory
3.2A$3.A7.A$2A.A6.2A$A2.2A6.A$.2A4.A$3.5A$3.A4.2A$4.2A2.A$6.A.A$6.A.A
.A2.A$7.2A.4A$9.A$9.A.A$10.2A!
That makes them useful for hassling traffic lights, if nothing else... See for example the p29 and p58 oscillators in Dean Hickerson's stamp collection (in Golly's Patterns/Life/Oscillators/).

By the way, I though this were up to something, but input is nearly impossible, one of the catalysts are destroyed and the output isn't useful. Triple damn.

Talking on patterns... Is this herschel-to-honeyfarm already known? (I wonder how many times I already asked the same question XD)

And a bi-block puffer + "blinker fuse puffer" (or Igniter, as I call them) + Ecologist squad might render this pattern useful.

Being my thread low-traffic I'd like to point out a new possible glider-converting arrangement if the red dot that forms upon the glider's contact can be transformed into anything useful:

Code: Select all

x = 10, y = 11, rule = LifeHistory
E7.E$3E4.E$3.E3.3E$2.E.C$2.2E$5.D$2.4E$2.E3.E$3.3E$.E.E$.2E!
I have also found several other similiar interactions where only a single dot arises after a glider contact; and the catalog is here:

Code: Select all

x = 64, y = 11, rule = LifeHistory

The last one is probably the best, since a failure to use it results in a clean destruction. (But that's just my opinion.)

It can be made into a true glider eater:

x = 8, y = 9, rule = LifeHistory

But of course, this is already known.

Indeed. After all, using the dots is quite a difficult task. :P

And I found out this reaction to be semi-interesting for me:

Code: Select all

x = 13, y = 13, rule = LifeHistory
6.C$5.C$5.3C2$3.D$2E.2E$2E.E.E$3.E.3E$3.2E3.E$6.2E.E$7.E.E$5.E3.E.2E$
5.2E2.2E.E!
It seems the glider slightly converts the still-life above before destroying it because of a dot that is inevitably generated after 7 gens.

EDIT: And this super-tiny variation is easier:

Code: Select all

x = 9, y = 13, rule = LifeHistory
6.C$5.C2B$4.B3C$2ED2.2B$.E2.3B$.E.2E$2E.E.E$3.E.3E$3.2E3.E$6.2E$3.2E.

Thanks! I guess I remember that one from somewhere.. Anyways, I want to find new reactions, glider-to-dot converters where the dot is open for any catalysis.

Just out of curiosity, have this already been found?

If it was, it was marked as uninteresting by its discoverer. The discoverer was probably a search program for turners and splitters from glider collisions with closely separated spartan objects, though all such searches I know had a small bounding box and might not have actually gotten to the one you put.

Yours is uninteresting because one-time splitters and turners work with gliders, which are long-range signals, while Herschels are short-range; they need an immediate conduit or they just make the familiar dinosaur head. This would have been marked by the program mentioned above as an unsuccessful constellation and it would have moved on.

No real project of interest is likely to use both Herschel conduits and one-time-turners/splitters, so something with a little bit of each actually is useful to neither.

Can you please explain what the "dinosaur head" is?

Run Gustavo's pattern to T=72. You'll see a glider heading northwest, a 7-bit pattern heading south which is called a "Herschel", and some fast-fading sparks.

Keep running the pattern for another 128 ticks, to T=200, and (if you're running in Golly's LifeHistory rule or in LifeViewer with the standard theme) the Herschel's "reaction envelope" will appear -- upside down in this case. The dinosaur head is mostly made of blue OFF cells, and has a ship for an eye, a blunt nose, and a couple of blocks decorating the neck.

If you run any methuselah, you'll see Herschel-generated "dinosaur heads" popping up all round the edges of the active area. Acorn produces at least four, for example. R-pentominoes and B-heptominoes both naturally evolve into Herschels while moving a fair distance, so this is one of the most common ways that chaotic Life patterns colonize new territory.
