Probably minimal, unless there's some <10 cell edgy enough loaf predecessor that times just right.
Luckily, one such predecessor does exist!

Code: Select all

The wing sequence is one generation too late, which might be my fault, and in case that is the case, I'm sorry about that. Here's the fixed version:

Code: Select all

``````x = 14, y = 37, rule = B3/S23

By the way, when you found the transparent fishhook reaction with the two-glider octomino, why were you searching for O-accepting conduits in the first place? If it's because you have conduits that make clean two-glider octominoes, then dvgrn, I, and probably others would be interested in seeing them.
I have historically worked on conduits, but recently, I've been working on glider syntheses and investigating SnakeLife.

I haven't commented on that discussion because I have thoroughly forgotten what the CatForce search on the octomino was for--I do not even recognize that transparent eater. I think it might have had to do with catalyzing two-glider collisions in general to see if anything rare and useful happened?

I think that we should investigate the two-glider octomino because it seems to have a lot of uninvestigated potential. For example, here is a mostly-complete way to turn it into a century (with a demonstration of connectability attached):

Code: Select all

``````x = 32, y = 25, rule = LifeHistory
22.2A\$22.2A4\$13.2C\$13.2C\$11.3C\$12.C3\$4.2A\$2.A2.A\$.A.2A\$.A\$2A\$15.A\$14.
A.A\$14.A.A6.2D2.2A\$15.A5.3D4.A\$12.3A7.D5.A.2A\$12.A12.2A.2A.A\$26.A\$24.
A.A\$24.2A!``````

There are alternative ways to suppress the toad, but I haven't found any with better input clearance.

Code: Select all

``````x = 23, y = 22, rule = LifeHistory
20.2A\$20.2A4\$11.2C\$11.2C\$2A7.3C\$A.A7.C\$.A7\$13.A\$12.A.A\$12.A.A6.2D\$13.
A5.3D\$10.3A7.D\$10.A!``````

Code: Select all

``````x = 22, y = 22, rule = LifeHistory
19.2A\$19.2A4\$10.2C\$10.2C\$8.3C\$2A7.C\$2A7\$12.A\$11.A.A\$11.A.A6.2D\$12.A5.
3D\$9.3A7.D\$9.A!``````

Code: Select all

``````x = 25, y = 22, rule = LifeHistory
22.2A\$22.2A\$4.2A\$4.2A2\$13.2C\$3.A9.2C\$2.A.A6.3C\$3.A8.C\$3A\$A6\$15.A\$14.A
.A\$14.A.A6.2D\$15.A5.3D\$12.3A7.D\$12.A!``````

Edit: I just found a way with better input clearance.

Code: Select all

``````x = 21, y = 22, rule = LifeHistory
18.2A\$18.2A4\$9.2C\$9.2C\$7.3C\$8.C4\$2.2A\$3.A\$3A\$A\$11.A\$10.A.A\$10.A.A6.2D
\$11.A5.3D\$8.3A7.D\$8.A!``````

Another edit: I was trying to complete an O→W partial that I found.

Code: Select all

``````x = 39, y = 27, rule = LifeHistory
38.A\$36.3A\$2A33.A\$A3.A30.2A\$.4A\$13.2C\$.2A10.2C\$.2A8.3C\$12.C3\$37.2A\$36.
A.A\$36.2A4\$32.2A\$32.A.A\$34.A\$34.2A3\$22.2D\$23.D\$21.2D\$21.D!``````
It took me at least five minutes to find a shape to replace the fishhook with that would perturb the activity in the same way and cleanly annihilate the boat.
Do you suppose that we can get an O→L out of this?

B2n3-jn/S1c23-y is an interesting rule. It has a replicator, a fake glider, an OMOS and SMOS, a wide variety of oscillators, and some signals. Also this rule is omniperiodic.

Wow, that's not just a new record -- I think it kind of blows all previous records along these lines out of the water. Even the "kaleidoscope" symmetric-soup variants of this kind of crystal growth/decay behavior (of which we had a lot of examples even a year ago, haven't checked recently) tend to survive only 5 million to 25 million ticks. I think the outlier was 64,935,262 ticks. But that was a symmetric soup, where this kind of thing happens much much more frequently.

There's a particularly big sudden jump in the crystal's active location due to something that happens at (620170, -619980) @ T=50892900, though the new active site ends up being 500-ish cells northeast of there.

### Re: Soup search results

I've wondered for a while now - were such a soup to produce a glider that goes back up to the switch engines in question (assuming that's possible in the first place), and prevent them from growing the population further at all, would this constitute a proper mesuthelah or just another one of these cases here?

Q: How do you tell a real conwaylife.com forum member from a sockpuppet?
A: Only sockpuppets ever agree (with their controllers) about the precise definition of "methuselah".

My personal opinion would be that if one of apgsearch's random soups managed to shoot down its switch engines after a long delay and stabilize its population, that would constitute a bona fide methuselah (which would probably break the longevity method by quite a large margin).

It's pretty certainly possible for a soup to naturally spit out a pair of switch engines that produces backward gliders, and the switch engines can be destroyed by one or more forward gliders with exactly the right timing. Some mechanisms along those lines exist and are required for RCT cleanup, among other things.

It's just really really I-don't-know-how-unlikely for the two switch engines and the gliders to both be generated by the same soup, and for the backward glider stream to just happen to not drill through the soup's debris before anything interesting happens, and for a spontaneous eater not to show up on the glider stream, either.

I don't agree. Crystal-based weirdness is just a totally separate category from the settling time for regular random ash, which seems to follow a nice predictable probability distribution.

Yeah, those are difficult to form naturally. A good way of coming up with one of the rarest n-bit still lives is saying "n-bit snake", at least for suitably small n (read: this will hold for all n up to about a few million or so).

A few million?

Object rarity tends to be a function of the lack of small predecessors. A 500000-cell snake could be made by the following simple predecessor together with a distant target:

whereas a 500000-cell random.rle-style still-life in a bounding box of slightly more than 1000x1000 seems very unlikely to form naturally.
What do you do with ill crystallographers? Take them to the mono-clinic!

### Re: Soup search results

Object rarity tends to be a function of the lack of small predecessors
Can we measure that correlation empirically?

A few million?
I guess I was underestimating the commonness of… (looks at chart) pretty much everything.
Each day is a hidden opportunity, a frozen waterfall that's waiting to be realised, and one that I'll probably be ignoring

Yeah, those are difficult to form naturally. A good way of coming up with one of the rarest n-bit still lives is saying "n-bit snake", at least for suitably small n (read: this will hold for all n up to about a few million or so).
Personally, I would go with this:

Code: Select all

``````x = 21, y = 21, rule = B3/S23
17b2obo\$17bob2o\$15b2o\$14bo\$14bo\$12b2o\$11bo\$11bo\$9b2o\$8bo\$8bo\$6b2o\$5bo
\$5bo\$3b2o\$2bo\$2bo\$2o\$o\$bo\$2o!``````
However, I'm sure that anything with over half of its cells in long stretches of diagonal lines will be near the bottom.

Object rarity tends to be a function of the lack of small predecessors. A 500000-cell snake could be made by the following simple predecessor together with a distant target:
Then again, every glider-constructible object has a predecessor with sixty-four or fewer cells—and this number is probably lower if one uses alternative switch engine predecessors or my idea to save a glider by using 180° gliders to create the target or targets works.
I have historically worked on conduits, but recently, I've been working on glider syntheses and investigating SnakeLife.
