I reduced the cost to 46 by making the block+R region near the beginning with three gliders instead of four and making a partiall delayed domino spark with three gliders instead of four.

It's currently at 47 gliders, but I strongly suspect that the tub-with-tail-bridge-loaf motif could be replaced with something that's cheaper to add. Any improvement would at least make this method tied for most efficient, and cheapening it by at least two gliders would yield an outright lower cost than anything we have so far.
For reference, my first version of this method cost 54 gliders, so the fact that I have already been able to reduce the cost by seven gliders so far with my rudimentary component knowledge demonstrates that maximum efficiency is not guaranteed and thereby suggests that further improvement is possible.

Thank you for informing me. If I copy and paste my syntheses into the bottom of the box at https://catagolue.hatsya.com/syntheses, is that enough to ensure that they will be added to Catagolue once the relevant issue is fixed, or is there some repository-thread where I should put them in order to prevent them from being forgotten? (I suspect from the fact that staging has been running okay that the answer is the former, but I figure that I should check.)
I am tentatively considering myself back.
