Here's another batch of catalyst finds, grouped by region then by usefulness. The first two catalysts in the H row were found by taking some low-clearance bespoke barrister find then welding on stuff to try to make them survive longer--the new Barrister (Barrister2 in the glanceless branch) handles ...

Anyone have a use for an H-to-three-quarters honey farm conduit? This is so tidy it seems like it's begging for an application. x = 27, y = 37, rule = LifeHistory 4$16.2A$16.A.A.2A$18.A.2A$6.A11.A$6.3A6.2A.A.2A$9.A5.2A.2A.A$8.2A11.A .2A$21.A.2A$20.2A$20.A2.2A$21.2A.A$11.C$11.C.C$11.3C$13.C8$7.2A$6.A...

This catalyst combination uses a glider to rotate a beehive by 90 degrees:

Cross posting from the "let's find a g-to-x" thread, here's a G-to-beehive. Partial by me and completion by iNoMed. Solved the reaction in the rightmost column of row 5 using a previously-discovered hyper-edgy beehive eater: x = 22, y = 27, rule = B3/S23 6bo$2o3bobo$bo3bo2bo$bob2obobo$2bobobobob2o$6...

EDIT: Here's something delightfully weird and spartan. I haven't found a good way to cleanly extract one of the B outputs, but I'm sure there's something that doesn't require resorting to Bellman: x = 34, y = 35, rule = B3/S23 $10b2o$10bobo7bo$12bo5b3o$12b2o3bo$17b2o4$30b2o$9bo20b2o$10bo$10b2o14b o...

Though there might something better, we have many glider-to-sparky mess and/or hive factories to play with now I hadn't considered using those! Looking thru barrister results on the speed tunnel from a previous search, I found something that works: x = 42, y = 58, rule = LifeHistory 21.2A$21.A2.2A$...

Ljkiernan1 found a glider reflector partial There's also the possibility of using the glider to eliminate the beehive, and getting output from the upper left area instead. Here's a near miss on a G-to-H, using a speedtunnel derived solution for that beehive: x = 50, y = 48, rule = LifeHistory 14.2A...

I don't see a way to get rid of the tub without ruining the input clearance, so I'll leave this here as a pi-to-(tub+impressive spark) x = 23, y = 22, rule = LifeHistory 15.2A$15.A2.2A$16.A.A.A$15.2A3.A$15.A2.A.A.A$16.2A.A.2A$17.A.A$3C13.A 2.A$2.C14.2A.2A$3C15.A.A$18.A.A$19.A$6.D8.E$5.D.D6.E.E$6.D7....

Here's three new H conduits: HBx226, HL154H, and HR184H. The output is a bit finicky on the first two. I'd also like to find a better cleanup for the last one, that only uses the FNG of the output. The leftover block is just one lane closer to the glider than for the sparky eaters in the B-to-H's (u...

This can be welded with an eater 2 and ship to make another conduit x = 16, y = 20, rule = LifeHistory 3.2A5.A$3.A5.A.A$4.A4.A.A$.3A.A2.2A.2A$A4.A$A.A.A.4A.2A$.2A.A.A2.A.2A $5.A$14.2A$13.A.A$13.2A6$C$C.C$3C$2.C!

This is perfect for a Hf factory though, you don’t even need to get rid of those blocks Nice eye! That escaped my notice. This seems promising! Instead of shooting down that extra beehive afterward with a glider, you could try to make it transparent: with how common honey farms are, there's probabl...

Pi-to-B with bad input clearance. Can't find anything that connects.

Strange glider eater with a transparent pond: it's basically a failed block catalyst. The spark is edgy enough that it might come in handy somewhere. Also just an interesting catalysis, showcasing the flexibility of the pond. x = 65, y = 20, rule = B3/S23 7bo39bo$8bo39bo$6b3o12b2o23b3o12b2o$20bobo37...

Crossposting: I came across this H-to-(G plus edgy unnamed region) yesterday in an old discord message from Kazyan and found a H-to-B with it (see the "hunting of the elementary conduits" thread). There's probably more to be found. Most useful catalyst placement found yet is marked. x = 38, y = 36, ...
