On 2015-10-12 (page 28), chris_c posted several improved syntheses which I have in my updated database, but which still haven't been updated on the web site:
The first (this one) from 9 gliders. This new one is an improvement!
The second (fox) from 9 gliders, one less than the new one.
The fourth (by flops) from 11 gliders, one less than the new one.
(However, in retrospect, your 8-glider synthesis of why not (see next paragraph) reduced this to 10, as 2 gliders can remove one bit. I hadn't noticed this before, but this post brought it to light!)
Also: The third one (hexapole) from 10 gliders by chris_c and later reduced to 9 by BlinkerSpawn on 2016-08-23, so the new one from 8 is better. (This improves 52 syntheses, and affects secondary syntheses for 5 others (all larger barber poles, and all pseudo-barber poles)!
The fifth also from 12 gliders by Extrementhusiast on 2015-01-05.
The sixth (why not) is the same one you posted on 2016-08-23.
The seventh from 11 gliders by me on 2015-10-05 (page 27).
All in all, 3 improved syntheses (plus 51 derived ones) is pretty good!
