It may be possible to be extended into a tubstretcher:

Code: Select all

code
I tried my search program's hand at this and the longest partial it produced after a 129h search was:

Code: Select all

code             
or stitched back in in just the one phase:

Code: Select all

code
Unfortunately next search size down was <5h so next search size up is probably measured in months...
Another direction (pun not intended) is to find a partial that extends diagonally, e.g.

Code: Select all

x = 77, y = 77, rule = B3/S23

Yes it is; you just need to include the component you want to extend:

Code: Select all

x = 34, y = 21, rule = B3/S23

Another wave I couldn't tame. I was lucky with branching on the right, but not on the left. It's 2c/4 and leaves blinker trails.

The repeating part was also found with Nicholay Beluchenkos toroidal version of WLS. The corner was found by a custom search with wls0.71.

The setup of the toroidal part might be interesting for you:

Period = 2 (!)

Colums = 80
Rows = 16
Lower edge glued to the upper (slide 4 cells right)
Left edge glued to the right

Translation 1 cell right, -8 (!) cells down

In this way you force that the parts found attach to themselves with a phase shift of 2!

Only restrictions like that make search times acceptable! On the other hand these creative uses are what makes WLS so attractive as a tool for me.

If you want to know what elementary-based moving objects are known, you should look at the moving objects collection. According to the collection, this is the first 2c/5 puffer:

Code: Select all

There are many other 2c/5 puffers in the 2c/5-extended section. However, this might be the smallest known 2c/5 puffer by population and bounding box. I think the only other comparably small 2c/5 puffer is the following p15:

Code: Select all

x = 27, y = 14, rule = B3/S23

Does this have any hope of being synthesised? It's a puffing tagalong for an existing spaceship (30P5H2V0) with a 39-glider synthesis:

No tagalong-adding reaction is likely to work with the existing 30P5H2V0 synthesis, but the entire puffer looks amenable to Goldtiger's LLS-based approach to synthesizing medium-sized ships. A synthesis attempt could fizzle out due to unforseen difficulties, but I'd put this under a solid "hope".

Yeah, where there's Life there's hope, as they say. I'm no longer placing any nickel bets against the constructability of objects under 100 cells, let alone under 60 cells.

As Kazyan says, it seems likely to be easier to build this all at once with a new synthesis design. The tagalong is on the edge of the spaceship, but still ... 2c/5 is faster than c/4, so there just aren't very many options for catching up to the back of an existing 30P5H2V0 with some kind of *WSS or flotilla, to place the front part of the tagalong. It's going to be tricky to get any decent level of control over collapsing the *WSS at the right time to get the tagalong.

I mean... maybe there's some impressive new technique for building super-tricky seed constellations, that implode and travel sideways to hit a small *WSS flotilla and produce the tagalong just when the 30P5H2V0 is going by. But that still seems like a painfully constrained search space.

There might be a way for the puffers to rephase each other, resulting in a puffer (or possibly, although not probably, a spaceship) of a different period. Here's one partial, which would be p30 if completed:

I was running a search with WinLifeSearch for a spaceship, and I found one I'm not sure has been discovered before. It has a period of 2 and (I believe) a speed of C. Code:

First of all, it moves at c/2, not c. Lightspeed spaceships are impossible in Life. Second of all, that's a nice (probably re)discovery, but c/2 ships aren't usually of much interest. Here's a 200 cell long c/2 ship found with rlifesrc:

It has probably never been discovered before, but it's still not interesting. c/3 is not vey interesting either.

That's just Dean Hickerson's (?) old wicktrailer, one of the first c/2s to be discovered. I believe p2 c/2 is pretty much dead - reasonably small ships are enumerated, large ships are pointless, and it's completely within reach.

It can accommodate a small tagalong that is already known for other c/2 spaceships (and possibly for this one).

The tagalong can also be placed on the other side.
I am tentatively considering myself back.

Chris Rowett found a new p120 2c/5 puffer. It can be reduced to this very small form:

Does this have any hope of being synthesised? It's a puffing tagalong for an existing spaceship (30P5H2V0) with a 39-glider synthesis:

{alien rle}

It's sub-c/2 so perhaps the tagalong can be added to the spaceship?
