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):

Four of the catalysts are doing triple duty now.

Also, the catagolue queue seems to be stuck again, anyone know why?

I don't know, but it's been stuck for a while (EDIT: yes, it is stuck still)

well, shrunk that p1815... I did find another still life that allows the output glider to be on a transparent lane, and here that means 1 row and column less:

Addendum:
Actually, it can be shrunk by a lot more... 47x65 = 3055

Code: Select all

Forum Rule 3A - Don't doublepost without good reason (EDIT: also your 2nd RLE in post 2 could also have just been a replacement of the 1st).

Also fixed orientation and switched to plain RLE (no need for gun LV to be in history, since it can't be uploaded to Catagolue in that form) - gliders in guns also need to be pointed SE & at be at the edge of the Bounding Box (also preferably long side horizontal, but less strict as a rule)

Code: Select all

x = 64, y = 46, rule = B3/S23
