While that still life is indeed not #70, it's fine because #70 dropped off the list anyway. Someone added a stealth improvement to the base still life for #70's synthesis, which dropped it to 16G.
An idea for #210. The two distinct reactions at the bottom (pointy end of a LoM explosion and the domino inserter) might both be replaced by inserting the red cells at generation 40. The base still life,
xs17_g88b96zc952, costs 12 gliders but looks like it could be done in...8, maybe.

Idea for #266 and #267. On the left, the red cells should appear in generation 15, and a 4G inserter should be found for the double dot spark that doesn't involve the yellow glider. With everything in place, the snake inserter on the right would have room to appear.

The current 17G synthesis for #135 is below, but with a cleanup glider removed in the intermediate step. This would be a 16G solution, but there's a single random blinker.
Neither of the 3G versions of the spark generated by the four marked gliders fit here, but I'm certain that a 4G version could both form the spark and delete the extraneous blinker. There's plenty of room to wave around the glider in white, but there does not appear to be a solution just by doing that, from my manual testing. A different mechanism for the spark may be needed.

Now we're down to only 6 17-bitters left! 4 of those are pretty similar.

I had pushed an RLE of the last six stills only a few posts above. Why would you want to be relentlessly up-to-date?

A possible longshot approach for #267:
Code: Select all
x = 26, y = 11, rule = B3/S23

Since the precursor SL takes 7G, all for separate transformations would have to be done in 9G (clearly a tall order -- 11G seems like a more likely lower bound, 1/3/4/3 clockwise from bottom, with 13G probably more realistic). I wouldn't be surprised if the precursor SL could be reduced to 6G or even 5G with luck, though -- which would open an outside chance of coming in under 17G for the SL.

I was also expecting a solution that could solve both Tweedledee and Tweedledum at the same time by flipping a snake insertion, but I was never able to get anywhere close by trying methods like that. So Goldtiger pulls through again. Sure enough, #113 is probably doable, since a base can be made in 11G and there's a 4G budget for the spark in a relatively simple activation step:
Code: Select all
x = 72, y = 28, rule = B3/S23
