Oh my god, 2021 is almost over! This has been a very fruitful year in discoveries, indeed! (well, I can't say much, since this is the only year I've been active in.)

I suspect that a functional ElemSrch would reduce some of the larger guns. Above about p550, prime periods start to get dicey and fall behind the usual standard for snark/syringe technology, but custom Herschel tracks don't really have that problem.

If not stable, how about periodic ones? EDIT: I just saw its potential. When finished with good clearance, it should be a replacement catalyst for an eater 3 in cases where the loaf hits an asymmetric pattern and becomes a 2bo$2obo$4bo$3bo! spark, or that for a ship when it becomes a 3o$3bo$3bo!

You get an Annoying Beehive or you get nothing. It's in the rules somewhere.

More seriously, though, that's a great-looking conduit. Props.

popseq was able to find a 4G replacement for the phi spark and beehive:

On page 187, the replacement for an eater 1 in the color-preserving semi-snark is described as a conduit. The object is a catalyst, not a conduit. [ NJ Oct. 4: Fixed. We added a new subsection 7.1.1 ("conduit naming") that actually introduces catalysts now as well.] 10/4 All reports in this post hav...

What p2 catalysts do we have? I can only think of these two: Also, is there any way to search for possible phase-shifting p2 and p3 catalysts, for the sake of prime periods? Some observations that are relevant to these questions: - p2 catalysts are apparently harder to look for, according to LLS. I...

Sparking oscillators have been used to modify reactions since time immemorial +/- a few generations, but recently, there has been growing interest in a new kind of oscillator that behaves more like a catalyst than a dot-dispenser. This thread is for those. To start things off, in the p54 gun, a vari...

-- Where did that transparent-boat 2G->G reflector come from again?
