Synthesising Oscillators

[mniemiec]

"very" reported a new bizarre 24-bit P2 in a soup on the Discord yesterday.
From the soup, I was able to develop a 19-glider Rube-Goldberg synthesis: ...

There are also the following stator variants, also 24 bits, that may be more difficult to synthesize: ...
EDIT: It would probably be easiest to start with a base still life: ...

Unfortunately, the only reason this oscillator was found at all (and a subsequent synthesis was able to be developed) was because it happened to pop out of a soup. I just checked Catagolue, and none of the other stator variants have done so (yet).

It's true that if a way could be found to add the rotor to an existing still-life, this would provide syntheses for the other stator variants, and many other larger ones as well.

During my work at making a p256 construction arm for RCT project, I've used this conduit quite a few times:

It uses figure 8, and here's the synthesis of it I have:

Code: Select all

x = 18, y = 21, rule = LifeSuper
8.4H2.4H$9.4B4D$10.6B$10.7B$10.7B$9.7B2C$.2A7.2B2CB.2C$A2.A2.2B3.CBCB

Unfortunately, that synthesis doesn't work for the conduit, as the eater is too close.
Is there some synthesis for figure 8 that would work here and be not much costlier in terms of slow salvo synthesis?
If there isn't it's not a big problem, I think I have ways to deal with it.

I don't know of any figure-eight seeds with better clearance than that.

It seems like a lot of natural figure eights show up due to this particular collision between a pi and a LOM --

Code: Select all

x = 7, y = 8, rule = B3/S23
b3o$bobo$o2bo$obo$3o$4bo$3b3o$2b2ob2o!

Code: Select all

$2b3o!

-- which is not helpful because it doesn't fit any better than the known seed. There could well be a hint among the hundreds of Catagolue soups, but it seems like 90% of them are basically this reaction.

It doesn't look like any of the syntheses in Mark Niemiec's collection offer any useful clues for a super-edgy figure eight, either:

Could the eater be added in last? There might be some options along these lines:

One-sided version of natural P6 domino sparker from 26 gliders; two-sided version from 44: ...

These ten (known) oscillators can use this instead of 64P6. Are any of them newly synthesizable? ...

The new synthesis requires many incoming gliders arriving from the spark side (e.g. if the spark faces north, many gliders must come in from NE and SE). Because of this, creating two sparkers facing each other would be difficult, unless there's a large separation between them. Also, the active hassled object would the needed to be added later, from east and west.

Ones with pairs of sparkers side-by-side (e.g. rightmost one on 3rd row) would be difficult, because the mechanism that activates the edge of the house of one would likely interfere with the other one.

Ones with pairs of sparkers at right angles to each other (e.g. leftmost one on 3rd row) would likely be even more problematic, as half of the activation gliders of one of them would be coming through the other one - requiring a fair bit of re-engineering.

Ones with eight sparkers in a circle (e.g. middle one on 3rd row) would multiply that problem fourfold, and in addition, the activation gliders for the last few sparkers would have to come from *inside* the oscillator - and once those were complete, one would need to inject eight R-pentominoes inside the arena entirely through the narrow cracks in the side. I don't think we're going to see this one synthesized any time soon (although seeing some of the engineering marvels that various people have come up with in the past couple of decades, I'm not saying it can't happen.)
