Spaceship Discussion Thread

People find that from time to time, but nice catch.

Thank you. Suppressing that birth for one more generation and suppressing another birth makes it move at 2c/6, but unfortunately, the mechanism of suppression at the front requires a very unlikely spark except in Symbiosis.

Honest question here. Why make this big list of small ships? I don't get the point of listing every single combination of tagalongs. Just a list of freestanding ships, components, and tagalongs would do, wouldn't it?

The bottom center part looks like the back of a MWSS. Shall we call this a long MWSS?

[Sokwe]

Honest question here. Why make this big list of small ships? I don't get the point of listing every single combination of tagalongs.

There are a few reasons. First, I personally like a definitive list of all of the smallest known ships of a given speed. Further, these collections are just extensions of previous lists. Also, not every tagalong connection is obvious, and it's hard to know where to draw the line on which should get included and which shouldn't.

Just a list of freestanding ships, components, and tagalongs would do, wouldn't it?

I actually maintain just such a collection for 2c/5 ships. I don't have such collections for lower-period ships, because the number of "components" and the complexity of component connections again makes it difficult to decide what to include and what to leave out. For example, consider the small c/3 component at the tail of several c/3 ships:

Code: Select all

x = 70, y = 28, rule = B3/S23
30bo26b3o$23bo5b4o19b2ob2obo$22bobo3bo3b2o18b2o4bob2o$21bo3bo3bo4bo16b

3bo3b2o23b3o$9bo11bo3bo3bo4bo17b2ob2obo$6bob2o12b2obo5bo20b2o4bob2o$6b

3bo3bob3o$7bo21bo8b2o3bo12bo8bobobo$38b2o19bo3b2o3bo$7b2o19b2o25b2o3b
2ob2o$63bo$9bo20bo26bo$7b2o19b2o25b2o$7bobo18bobo24bobo!

The leftmost ship is the smallest known ship that contains this component, and it's required for the ship to function. But the component can be used as a tagalong in ways that I don't think are obvious. If I made a collection of just ships with unique components, I would have a hard time deciding whether to include only the first ship, the first two, or all three.

Edit:

The bottom center part looks like the back of a MWSS. Shall we call this a long MWSS?

There are a large number of 2c/4 ships with that same component. I also fear "long MWSS" would just be confused with the HWSS or OWSS.

A sparky spaceship by Sokwe I had neglected to try in my exploration of c/4d puffers leads to this p32 beehive puffer

This may have been noted already, but a p32 c/4 puffer gives the same spacing as a p96 c/12 puffer. Here is a growing spaceship based on this:

who discovered it?

Now that is another surprise discovery! The first tagalong for the weekender in years!

I guess it can be disturbed to generate puffers...

According to Catagolue's "attribute" endpoint, it's winston (who's been mostly active on the discord but also posted on the last page of this thread).

Like the fireship, this tagalong is composed of two R-sequences. Should we try putting R-sequences (and probably P-sequences) after every spaceship with back sparks since their commonness makes them likely to spawn again?

The ikpx2_stdin census (where this was found) sort of already does that, since it evolves decaying partials to see if anything interesting pops up, like here. I'm not sure if every velocity has been run through though - this sort of thing is more exciting at rarer speeds like 2c/7.

I guess that you have a point. I'm just wondering how it took so long after the fireship to find this.

That makes the list of objects that we can make cleanly at 2c/7 beehives, gliders, and blocks (although now that we can make gliders cleanly, we can probably make other objects via glider syntheses).
