Exciting to see new this approach being viable. I'll wish a new period oscillator be found.

LOL, you too

Meanwhile, I'm just over here stabilizing a P8: Great work! Here's a reduction of the p4 supporters. (Which is, by the way, stable by itself.

I just read the paper and cannot relate what this has to do with their point. For a layman like me the gist of the paper, I think, is trying to say: It's easier to say ~~"Spider"~~ Nope, wrong name; "Smallest c/5 spaceship" rather than the RLE of it. which seems to be generally true with objects com...

Reduction of the p88 pre-pulsar shuttle: And that's a drastic reduction. Well done!

Oh no! Thanks for testing, and thanks a LOT for reporting the errors. This
Yeah, this probably means I have to do the packaging also on Ubuntu 14.04, not only building it. I'll start fixing it now but it'll take a while.

Is there a universal 2-lane monophase slow-salvo toolkit?

I guess the question is "basic" as in "basic research"? : )

Just a self reminder; I'm trying to fix this by building an AppImage of Golly for Linux.
It would be helpful for the users to report any missing libraries.

Wow. That non-obvious completion with the pipsquirter is truly a piece of art.

Looking some more at the osc-supported section of jslife, I noticed that one of the p72 reactions could be supported by Elkies' p36:

Beautiful.

I compiled Windows binaries for some of the SAT solvers here.
(Edit: Due to licensing issues, moved the repo and distributing it as GPLv3. Using it wouldn't be a problem though.)
CryptoMiniSat offers Windows binaries, so didn't include those.
Any questions and comments welcome.

The new p23 will be called David Hilbert. The reference should be obvious.

We should probably leave the naming to the discoverer. Unless AbhpzTa is fine with that one.

Seconded. And may I question about the reference? (Not obvious to a non-english-meme speaker)

Are the 1H3, 2H3 and 3H3 pentoads known?

Maybe, but it's trivially constructible anyway. Still it's a nice demonstration on Block-keeping components.

May I ask a small question regarding SAT-based Life searching in general?
I'm working on a thin wrapper for Life-searching on Z3. It's currently working, but several times slower.
I'm curious if this was your experience with SMT solvers as well, or was it different?

Here's a smaller p7 pipsquirter; not sure if it's known. x = 14, y = 20, rule = B3/S23 5bo$5bo2$3bo3bo$b3obob3o$o4bo4bo$b4obobobo$4bobo4b2o$b2obo2bob2o2bo$2b obo3bobob2o$2bo2bo4bobo$b2o7bo2bo$6bo4b3o$7b4o$11bo$6bobob2o$4b3ob2o$ 3bo3bo3b3o$3b2o2bob2o2bo$8bobo!

@EV2 @Moosey @A for Awesome EV2 might wanted to point out that this is two **known** discoveries combined. One is the front reaction, which I saw from the forums quite a long time ago, and the other is the 3c/14 partial. Unfortunately it doesn't make a 3c/14 ship more likely, but it's an interesting...

So here's the place for a big congrats, eh?
Congrats to everyone involved, seeing the process on discord I can tell it's a lot of hard work.

This might be known, but a group of p4 sparkers contain a versatile "sliding domino" component I'd like to share: x = 37, y = 68, rule = B3/S23 14b2o$12b6o$10bo2bo2bo2bo$6bobobobob2obobobobo$4bo2bo14bo2bo$4bo20bo$ 5bo2bo12bo2bo$8bo12bo$7bo14bo$8b3o8b3o$10bo8bo12$6bo$2o3bo2bo10bo2b2o$ o2b2obobobo6bob...

Currently was able to use that program with no big problems.

Welcome to the forums! Has anyone studied these? Not sure if there was an official study or written record of it. I remembered the "Mandelbrot set in HighLife" article as a similar experiment.

Nothing much, just yet another p7 bumper that seems to be welding-friendlier than other variants. x = 32, y = 23, rule = B3/S23 30bo$29bo$29b3o7$22bo$20b2o$3bo2bo14b2o$3b6o$b2o6bo$o2b2o2b3o2b2o4b2o$ 2obo2bo5b2o3bo2bo$bobo2b2obo2b2o4bobo$bobo3bobo2bo6bo$2obobobobobobo$ 4bobobobob2o9b2o$6bo3bo12bo$5b2...

A couple new oscs, including two related small-ish p7s (a couple uninteresting low-period ones included for completeness): Nice discoveries :) Maybe we could make something out of that p7 weak grin spark.
