I recall fighting with
xs16_ci52zw1i4ozw121 a long time ago, but yesterday I beat it in ten minutes:
Code: Select all

#CSYNTH xs16_ci52zw1i4ozw121 costs 10 gliders (true).
#CLL state-numbering golly

19b3o$21bo$20bo!
It was a more careful inspection of previous route, combined with a lucky choice of 3G blonk-tie recipe, that made it.
Around 70 syntheses were reduced by implication.

xs16_4al9aczx56, previously converted from
xs15_4al9aczw23, now in 8G based on
a randomly picked C4_4 soup, thereby influencing

Finally, thanks to a
four-glider add-carrier component by carsoncheng,
xs16_0ck3146z4a43 is down to 9G. It has better clearance than another one quoted
here and lower cost than the old one:

Question: how many pre-block suppliers of this type (that is, capable of constructing aircraft carrier, snake or possibly beacon analogs) are known?
A lot, and collecting them proves to be quite laborious. Even a block on cover at block on cover (xs24_c89n8brz33032) synthesis would count, and I made things like these for fun:
