Synthesising Oscillators

6 spaceships up to 32 bits

I'm fairly certain the following two ships also don't have known syntheses:

Thanks. I didn't know about these two. Does anyone have a definitive list of small spaceships? Other than spaceships with known syntheses, I was going by pentadecathlon.com, the wiki, and trivial extrapolations and combinations of smaller 2c/4 ships.

Does anyone have a definitive list of small spaceships?

Edit: I decided to answer this question in another thread.

Can this eater-tie-beehive be placed as close as it is? I don't want to dig through Catagolue for edgy syntheses if we already know how to do that.

This is great! It would allow synthesis of the one problematic eater block frob, and potentially most larger ones where the frob still-life cannot be added in place. Unfortunately, all the ways I know of to make the activating still-life (13.238) come from the other side, so a better way will need to be found.

To make this specific to just this one synthesis, the frob still-life (14.294) could probably be added, but again, any way I know of to do so requires going through the eater still-life (which is why this one synthesis remains unsolved). It was particularly difficult, as the frob still-life must be created in one step, fully capable of eating the moment the head appears. With this converter, that constraint is removed, so it might be able to form it incrementally.

[Kazyan]

Hacking at it some more, I've reduced the problem to just growing an eater head into a boat in tight quarters--is there a known component for that?

I feel like there was an already-known eater-adding component that worked with that -- maybe in the soup search results thread. It might have been an integral with boat, though, but either way it would solve this.

Final step for another p2 on the list. I don't know how you would make the two nonspartan objects in the center, but they don't look that hard:

I found several syntheses using that, but none of them wouldn't interfere with the other non-spartan object. This is the best I found:

Excellent!

Even though this is not directly related, this prompted me to re-examine all my eater block frob
variant syntheses and to update them to be synthesized from as many directions as possible
(i.e. cheapest, starting with frob, starting with block, starting with frob+block).
I hadn't previously considered the ones starting with the eater, but it turns out that integral w/up boat can easily be added in place, and doing it this way actually reduces many of the syntheses, using this converter:

Code: Select all

x = 78, y = 20, rule = B3/S23

51bo!

Of the 24 syntheses up to 24 bits, 12 are improved. I haven't finished the 25-bit ones yet, but some of those are also improved.

I feel like there was an already-known eater-adding component that worked with that -- maybe in the soup search results thread. It might have been an integral with boat, though, but either way it would solve this.

There are several; unfortunately, of the 62 oscillators I know of up to 25 bits, all could be built with one of those except for this one, as the hook on the frob part got too close to the eater in every case.

Sorry for that misconception. To make up for it, here is a final step for the second still-life above:

Code: Select all

x = 49, y = 26, rule = B3/S23

I wasn't able to make a full synthesis from that, but this is how I was planning on doing it:

Final step for another p2 on the list. I don't know how you would make the two nonspartan objects in the center, but they don't look that hard: ...

This reduces it a bit by 6 gliders (LWSS to MWSS eliminates one cleanup glider on each side, and beehives instead of V-sparks):
