The mechanism looks known but I did not see it so far.
Edit1: The mechanism is in jslife p60 guns.

But after one period, (at p=120) your predecessor of the gun did not produce an LWSS, but increases the population to 75 (the glider) excluding the boat. And of course there are multiple ways to remove more cells similarly, e.g. block-> preblock.

I don't think so. After a full p240 cycle I can perfectly remove 2 LWSS.

It's disappointing in a way. The original gun was so clever, and yet we could have done this all along.

That is most likely because no-one knew that 87P26 (or 53P13) had a spark, and even so, no-one knew it was capable of eating gliders.

The reaction is well known and I think some other lifenthusiast made guns like that, actually.

I don't really know where to put this, since ceebo's collection seems to be unmaintained.

Here are slightly smaller p43 and p61 glider guns - at least smaller than those in the ceebo collection; it may be out of date. Using converters from the glider pair adjustment toolkit thread:

I don't really know where to put this, since ceebo's collection seems to be unmaintained...

The traditional location is a thread started by Freywa years ago called "Execution of Old Guns By Variable-Speed Firing Squad". I've cross-posted your messages there.

We're all hoping that chris_c's maintenance work is only temporarily suspended, since nobody else is very good at wrestling the various scripts into submission, to get updated READMEs and statistics.

[JP21]

I'm no good on this type of stuff. But, I made one. It's poorly optimized but I see no other guns for it. I will leave it to someone else to optimize it.

More optimized but not really because it still uses Fx119. I want to know if there are already smaller p240 copperhead guns.

I want to know if there are already smaller p240 copperhead guns.

The Stable Signal Converters thread doesn't seem to have any pointers to smaller guns. There's this p197 copperhead gun, which uses a recipe similar to yours but not identical -- and also this glider-to-copperhead converter which can be used to make any gun with period 197 or greater, just by swapping in a different input gun. It's 471x594, so definitely much larger than your fixed p240 gun, but also much more versatile.

Is there any way to reduce the cell count of this? I suspect that only one catalyst is required in the middle.

Yes! The catalyst worked! Wait; that glider on the left is getting close… Oh, come on!

Thank you. Now the LifeWiki page for the Gosper glider gun should be updated. (It currently states that twogun is the smallest known p60 gun.)

Actually guns are measured by bounding box, to give a sense of where you can slip one in, and because their population is unbounded anyways, and therefore twogun and the p12 filterer are both smaller.

Ah; thank you for explaining.

Does the smallest p90 gun use a period-tripling mechanism? I tried using a kickback reaction, but that created an octomino that didn't settle quickly after more gliders hit it.

Yes, it does, for lack of better guns at other divisors of 90 (which would be difficult):
