That higher-clearance insertion has now helped solve xs19_03p68oz39c32 and about eight relatives. I've been trying to make a component sequence to do this other transformation, as well. So far, no luck, but it's getting closer: x = 128, y = 13, rule = B3/S23 85bo2bo$89bo$84b6o$85bobo$4bo5b2o32bo39bo...

This isn't particularly the point, but a two-queen-bee oscillator has indeed shown up, "Berger's p30". In fact, a second instance of it appeared recently. http://gol.hatsya.co.uk/object/xp30_w33 ... cx33/b3s23

I do not know if there is any interest in this, but it would be nice to also have glider synthesis for non-still-life with small populations. The obvious caveat is that many syntheses tend to have left over debris that takes a few more generation to clear, which makes defining the notion of "succes...

Idea for these two xs19s, though I'm a bit at a loss as to how to insert the top red spark without interfering with the left red spark. It doesn't look too hard; I just can't figure out a way with correct clearance. x = 149, y = 31, rule = LifeHistory 88.A$88.A.A$88.2A2$137.A$86.A49.A$81.A4.A.A42.A4...

The takes care of three at-beehive still lifes! ...there are still more, because the motif is annoying and everything gets in the way of construction. Oh well.

Kazyan

There are still a number of still lifes with an at-beehive, simply because other parts of the still life get in the way of the existing at-beehive adders. This can get to an at-loaf, based on Extrementhusiast's adder, but I'm having trouble downgrading it back into a beehive. x = 112, y = 43, rule =...

Kazyan

Congratulations! That's a clever way to use the beehive-push reaction. Life is now one step closer to being omniperiodic.

Kazyan

I doubt there's anything special going on--that's just a non-obvious useful transformation and you happened to be the first to get it. Or perhaps there really is a steric hindrance problem in existing work. Here's a way to make certain corner beehive configurations: x = 298, y = 33, rule = B3/S23 13...

It's been a while since the original 16-in-16 project.

Spark_search is wonderful and has been pulling a lot of weight, now that it's public. :D There's a problem I'd like to report, though: when you copy anything onto the clipboard while the script is doing its thing, Golly freezes and puts up a blank textbox--at least on my machine, which runs Ubuntu. ...

Thanks for this. I've played around with L130 and haven't yet found a smaller gun using it, but there's probably one out there.

A result from Alex Greason's collisrc runs has revealed subtle bug (or non-feature) in transfer.py. The result is on the left here, but it works identically without the supporting table, as shown on the right. However, it appears that the transfer.py run only applied this component to objects with t...

That stabilization does allow for more empty space in the p16 gun, but for the current design, I don't think it helps reduce the overall bounding box. Some diagonal clearance--by making sure nothing gets on the red line here--would help. Currently, there's one cell that steps on it. x = 41, y = 31, ...

Kazyan

Indeed, at least two columns from the p16: x = 161, y = 161, rule = LifeHistory 95.BA$93.B2A.A18.2A.2A4.AB3.BA4.2A.2A$5.2A.2A4.2B3.2B4.2A.2A19.2A41.A .AB.A18.2A.A.B2.BA2B.2BAB2.B.A.2A$5.2A.A.B2.3AB.B3A2.B.A.2A18.A.3A38.

There are some still lifes characterized by tubs in a corner which, if they were eater heads, would be flush with an adjacent domino that prevents any of the usual eater-head-to-tub methods from working: x = 36, y = 29, rule = B3/S23 3bo8b2o8b2o8bo$2bobo7bo9bo8bobo$2bobo8bo10bo7bo$b2ob2o4b4o6b4obo$b...

Wow! How did you find it? I ran it through CatForce, per Scorbie's suggestion, with a maximum of two catalysts and centered on just one side of the ship. I found the two sides independently, both of which looked like clean deletions of that side. So I tried combining them on opposite ends of the sh...
