17 in 17: Efficient 17-bit synthesis project

#133 in 15G by improving xs16_35s26zbd. Its second soup had a really nice predecessor that could easily be mistaken for a synthetic solution.

EDIT: #62 in 16G. I'd previously made a mistake by submitting a version of the final step without the kickback, which is required for rewinding. If Catagolue figures it out, this still life will show up as taking 16 gliders. If it doesn't notice, than it will erroneously report 15.

#87 in, unfortunately, 17G. If there's a 2-glider way of activating the hat that I missed, this will become 16G. Either way, it punts #87 way down Catagolue's list of expensives.

There's a whole family of expensive still lifes based on a stabilized T-tetromino. Via component-bash: #193 in 13G, #142 in 13G, #141 in 16G (by combining the two), and #17 in 15G.

I suspect that there's a three-glider collision to replace the octomino+glider that produces no debris, although since the debris loaf is apparently the minimum possible debris for modifying the octomino, it'll need to pass through a different route.

#192 in 10G:

RLE

There's a whole family of expensive still lifes based on a stabilized T-tetromino. Via component-bash: #193 in 13G, #142 in 13G, #141 in 16G (by combining the two), and #17 in 15G. The synthesis for #192 could probably be directly adapted to get them more cheaply, as well as the rest of the members of the family.

There's another three-glider collision that provides the requisite consecutive dot sparks, but it doesn't work here, as it takes clearance from the side that needs it and gives it to the side that doesn't:

EDIT: There's probably a way to get #120 more cheaply via something like this. The red cell I've highlighted that doesn't belong in the still life needs to be off and stay off the entire time, though, and I'm not sure how to make that happen.

Turns out I had been using Niemiec's old figure of six gliders when calculating the cost before, but this method works even without the updated cost.

It might be reduced further, with something along these lines:

This may solve #249, but I haven't found reactions with the right clearance:

The base still life is 5G and the conversion from carrier to snake will be 4G, so the budget for the intermediate above is 7G.

There's probably a better way to achieve the penultimate step.

[Kazyan]

The facepalm method works much better!

#271 in 13G, using a +9G tail-growing method. I suspect #271 would have been solved automatically by Shinjuku, but it has an awkward shape, so the only tail-growing route that worked at the time was a +21G component-bash.
