Execution of Old Guns by Variable-Speed Firing Squad

[iNoMed]

p78 glider gun reduced to 37x41 (1517-cell BB) achieved by heavily optimising the p3 catalyst in the previously posted p78 gun design into a much smaller size:

In fact, this design is actually small enough to somehow reduce the p39 glider gun from 39x27 (1053-cell BB) to 40x24 (960-cell BB):

The last two have this awful-looking weld (done by hand) if anyone wants to try and reduce it

Also a population reduction to the p39 gun catalyst that allows me to orient the gun correctly:
EDIT: Irrelevant, because it was already reduced more.

EDIT 2:
I reduced guntrue_159 by flipping the tremi-snark (3496 -> 3128) and a large population reduction to guntrue_162 (reduced huge p3 weld).
Also, reduction to guntrue_380 via a 5x period multiplied guntrue_76, instead of a glider loop (3472 -> 2891):

p78 glider gun reduced to 37x41 (1517-cell BB) achieved by heavily optimising the p3 catalyst in the previously posted p78 gun design into a much smaller size:

Code: Select all

There is a lot of empty space above the p3 catalyst in this design. Might it be possible that a wider p3 could reduce guntrue_78 while still fitting into the red areas?

I'm pretty sure I tried that with LLS, and it came back impossible.

In other news, gun_19 reduced by one column with LLS (11286 -> 11187):
