Certainly a long shot, but it looks a little bit promising:

@simeks how about using a HF?
Edit: I see. Yeah, the ones you posted seems looks nice tobstart with.
Edit2: I think nobody ran Bellman with the loaf explosion?

[simeks]

@simeks how about using a HF?

There are certainly many approches, but this time I was looking for a target that emits an early natural 90 degree glider of the opposite colour, and that leaves an ongoing reaction that is not too exposive...

This is the most obvious I guess, but it has probably been explored pretty well:

Code: Select all

x = 6, y = 13, rule = LifeHistory
3.2A$2.A2.A$3.A.A$4.A7$3A$2.A$.A!

[muzik]

This "blinker meshing" stuff is actually kind of interesting. Not nearly as useful as glider syntheses, but cool nonetheless.


Beehive one:

Code: Select all

x = 7, y = 8, rule = B3/S23
4bo$4bo$4bo$3o2$6bo$6bo$6bo!

Spark coil:

[Kazyan]

Combining these doesn't quite work, even ignoring the side explosion that I didn't bother trying to tame:

I have seen a few CatForce outputs along these lines, though--two well-spaced beehives, in which one of them is opened up by the reaction into a Pi, which the other beehive restores. Nothing this handy, though.

The still lifes I know so far, that contain another photonegative still life inside them: ...

The number of still-life interiors that this can be done with is extremely limited. It's easy to show that the interiors of tubs (including all barges, long boat, and very long ships), carrier, loaves, pythons, ponds, mangos, shillelaghs, loops, and anything with an eater tail are toxic. This can be done with snakes of any length, so there are infinitely many solutions. I could only find the following viable ones up to 10 bits (although many of these can be modified into alternates containing the same inverted still-lifes):

As predicted, there is a simple sidecar-pi with repeat time 384, which is probably still very improvable.

The current H-to-G collection doesn't have many options for the lanes needed to kill that boat (SW -5, -8, -9, I believe). So I don't immediately see a way to extract any signal bigger than a glider -- but wouldn't be surprised if I've missed something.

The still lifes I know so far, that contain another photonegative still life inside them: ...

The number of still-life interiors that this can be done with is extremely limited. It's easy to show that the interiors of tubs (including all barges, long boat, and very long ships), carrier, loaves, pythons, ponds, mangos, shillelaghs, loops, and anything with an eater tail are toxic. This can be done with snakes of any length, so there are infinitely many solutions. I could only find the following viable ones up to 10 bits (although many of these can be modified into alternates containing the same inverted still-lifes):

Code: Select all

x = 49, y = 78, rule = B3/S23

An extension of row 3, column 3:

Code: Select all

x = 9, y = 10, rule = B3/S23

Don't know if further ones are possible.
