I suspect the base still life can be made in 8G to reduce the whole thing to 14, based on this:

This is slightly off-topic, but I noticed that 13.238 can be tightened up slightly, reducing it from 7 to 6 gliders. This may improve some other syntheses:
x = 35, y = 16, rule = B3/S23

Do you guys think that 15.786 can be taken off the list given an improvement on 13.82?
I'm pretty sure it's not on Catagolue (or just has 1 or 2 soups) and that seems like a somewhat plausible route.

That also gives 14.269 (EDIT: not 14.239) and 15.782 from 10. When and where was the improvement for 13.82 announced? I hadn't been aware of it.
