Is this three layers of hassling? We're hassling an R with unixes and a P42, which is itself a pulsar hassled by a P21, which is itself a honeyfarm hassler!

Thank you for figuring out a way to make it work. I wonder what other periods are possible. Could a stable version exist?

Is this three layers of hassling? We're hassling an R with unixes and a P42, which is itself a pulsar hassled by a P21, which is itself a honeyfarm hassler!

Additionally, a unix can be viewed as two blocks hassling a long barge.

[EvinZL]

The reaction looks bellaminizable, and there are probably catalysts which can clean up the junk. Also, for this conduit, the only possible period is 84 (since its two B42s)

I meant the period for an individual conduit, not a loop made of two copies.

Each has excellent fallback.

[Scorbie]

I'm asking this too late, but what do you mean by fallback?

[wwei23]

what do you mean by fallback?

The speed at which a sparker "runs away" from its own spark, I think.

[Scorbie]

Ah, makes sense, thanks :)

[MathAndCode]

The speed at which a sparker "runs away" from its own spark, I think.

That's part of it, but the amount of time for which the oscillator stays back is also important. For example, consider the reaction in which a domino spark turns a nephew of the century into a Herschel without its first natural glider.

Sparkers that do not stay back for long enough, no matter how powerful they are in other respects, cannot be used.

Only domino sparkers that fall back for long enough after delivering their spark can be used.

The distance that the sparker falls back is also important.

I found Jason's p22, although I tried other oscillators that turned out to not work first. A list of sparkers with the best fallback for each type of spark would be helpful.

[wwei23]

I found Jason's p22, although I tried other oscillators that turned out to not work first.

I mean finding entirely new oscillators, not finding known ones that work with the reaction. It seems like the period would have to be unimaginably high...

[goldenratio]

Well, higher period generally would equal greater fallback in your case. It would be impossible to support the aforementioned century reaction with periods lower than about 10 (which is too high to directly search new oscillators for)

[MathAndCode]

I mean finding entirely new oscillators, not finding known ones that work with the reaction. It seems like the period would have to be unimaginably high...

Unfortunately, searching for high-period sparkers is much more difficult than searching for low-period oscillators. That's a shame because high-period oscillators tend to have better fallback.

[wwei23]

Since then, I've realized the real strength of my P9 heavyweight emulator: Its fallback is far greater than its supporting sparker (It falls back at 3c for 2 generations straight, when the supporting sparker never falls back more than two cells). Even in the century reaction where it failed, the supporting sparker broke first.
