### (13,4)c/41 crawlers

Unfortunately it produces an extra block:

Code: Select all

``````x = 79, y = 119, rule = B3/S23
78bo\$76b2o\$77b2o21\$63bo\$62bo\$62b3o22\$48bobo\$48b2o\$49bo21\$34bo\$34bobo\$
34b2o21\$21bo\$19b2o\$20b2o21\$b3o\$o2bo\$2obo!``````
Gliders can come from a different direction:

Code: Select all

``````x = 78, y = 14, rule = B3/S23
75b3o\$75bo\$62bo13bo\$61b2o\$61bobo\$47b2o\$47bobo\$47bo\$33b2o\$b3o28b2o\$o2bo
30bo\$2obo14b3o\$18bo\$19bo!``````
There is a dirtier variant:

Code: Select all

``````x = 79, y = 14, rule = B3/S23
76b2o\$76bobo\$76bo\$62b2o\$61b2o\$63bo\$47b3o\$47bo\$34bo13bo\$33b2o\$b3o29bobo
\$o2bo15b2o\$2obo15bobo\$19bo!``````
And finally there is a way to burn a row of boats:

Code: Select all

``````x = 19, y = 67, rule = B3/S23

I wouldn't say it is reusable yet: blocks are on the other side from the glider salvo

### Re: (13,4)c/41 crawlers

From my waterbear work, that only demonstrates that a very particular track separation isn't rendered unusable by the blocks. It's good, but it isn't sufficient to demonstrate that a track can be reused. Producing SE gliders would solve the block problem though.
Physics: sophistication from simplicity.

It turns out that a helix for this speed exists at the period of the reaction itself, and it only uses 4 LWSS per period:

I haven't tried looking to see if a cheaper x2 (p82) helix exists, but the potential to avoid period multiplication altogether leads to an interesting situation here. If we can put together true-period 1x rakes/spacers and complete a spaceship like this, we may end up with a working p41 spaceship before we've found or proven the existence of a p41 oscillator. If this happens, I believe it would be the first time a period-N spaceship could be proven to exist *before* a period-N oscillator since the discovery of the glider in 1969.

Very nice! It seems to me like this helix could be reduced further to 3 spaceships per period. Here are the 4 basic interactions:

The problem is that the blocks block the previous gliders (albeit barely).

### Re: (13,4)c/41 crawlers

Well, given the same input, a block cleaner can be accomplished much easier, and there are plenty of ways to do so:

Code: Select all

``````x = 258, y = 9, rule = B3/S23
2bo49bo47bo50bo49bo48bobo\$obo47bobo48b2o49bo49bo48b2o\$b2o48b2o47b2o48b
3o47b3o48bo2\$7b2o\$7b2o48b2o\$57b2o47b2o148b2o\$106b2o47b2o47b2o50b2o\$
155b2o47b2o!
``````
One of them allows a clean chaining in two different ways, giving potential for rephasing:

Code: Select all

``````x = 67, y = 16, rule = B3/S23
2bo47bo\$obo48b2o\$b2o47b2o2\$15bo48bo\$14b3o46b3o\$4b2o7bo2bo36b2o7bo2bo\$

48bo2\$14bobo46bobo\$15b2o47b2o!
``````
And there is another one where a glider comes from a different direction:

Code: Select all

``````x = 15, y = 27, rule = B3/S23
6bo\$5bo\$5b3o2\$2o\$2o10\$12bo\$11b3o\$10bo2bo\$10b2o\$11bo\$13b2o\$11b4o\$10bo2b
o\$12bo2\$11bobo\$12b2o!
``````
That reminds me of 31c/240 track design a bit (but alas, there is still no clean overunity reaction).

Indeed, that is very true, but I might have not really made clear why we should bother with more complicated clean-up. As it stands, every crawler can only carry on with spark from active cells, which happily include gliders. So as far as the input goes, at least 1 glider is needed. Now the question is can we have a subunit of some kind that produces more gliders than it consumes, so far there are some ways, but one need specific still life configurations that are unclear how to obtain. Now, suppose you succeeded, but debris remains, then you need more gliders to clean, so that unit is not working as advertised. The crawler has a puny weak spark, and leave a block, so one can only break even using it. The much larger spark of that "clean fuse" could clear much more blocks than a simple glider can (in some configurations), and maybe some interactions can yield additional gliders.

As long as we do not have a way to produce more gliders than consumed, any crawler-puffer that manages so retain a period of 41 is worth mentioning at this point (I think), and this one is "clean", so I think we just should have it in mind.

Code: Select all
