Highly-forgotten indeed. I don't remember it and can't seem to find where it was initially posted. Can you provide a link? (Edit: link provided on Discord. See edit below for details.)

Crossposting this absurdly close p43 gun partial

On December 22, 2021 goldenratio posted alternate incomplete p43 gun partial result based on this reaction on Discord, including support from a single domino spark:

(the pentadecathlon obviously doesn't work, but it's just to show what i'm talking about.)

[hotdogPi]

Almost a p102 gun; we just need to delete the block. If one of the unices can replaced with a custom p6 sparker, it will work, and the bounding box will be 49×48 = 2352, much better than the current 3776. There are several spark locations that work that can delete the block, and fortunately, the unix spark and the block deletion spark must be on at the same time, making it easier to find.

Here's a 27x27 "QBless" period-30 glider gun (An improvement over the Pi-factory "QBless" gun (42x31) and an earlier single-QB completion of this design (30x28)), using a p6 domino sparker initially designed to reduce a p72 oscillator:

There could be potential for a single-engine design too, but IDK...

Edit: Turns out I was somehow comparing against the p79 gun (which is still 65x64), not the old p83 gun (83x52)...

Also, I moved your post to the gun discussion thread because the gun uses an entirely new engine, rather than being a reduction based on a known engine.
