Is this from-the-front LWSS inserter known?

I was not aware of that one, but the standard 3-glider method works just as well. Both insert at the minimum possible separation. Here are the other LWSS, MWSS, and HWSS syntheses I know that can insert spaceships at minimum separation (14, 16, and 18 generations respectively). Two had to be slightly tweaked:

A more compact p138, although it's still no record-breaker, I'm sure:
x = 82, y = 41, rule = B3/S23

On a related note, where can I find relatively-current versions of the gun collection?

chris_c's collection on GitHub is pretty darn current, and fairly easy to go look things up in -- you don't have to download the whole collection to find a specific gun.

(For the variable guns you might have to make some adjustments to get an actual gun pattern, though. That would be a good low-priority project if someone wanted to tackle it, building out actual RLE for each gun period up to 1000 where there isn't an entry in the fixed folder.)

If you just want to see if a newly built gun is better than what's in the collection, just multiply the all-phases bounding box length times width and check that against the number for that period, in the README on the landing page.

I swear I've seen this before. Wasn't it utilized in one of Guam's spark-to-G converters, or something along those lines? (Good work if you [re?]found it on your own, by the way :D)

EDIT: perhaps it was brought up in a discussion thread relating to said converters? Unfortunately I can't find anything with the forum search (partially due to "glider" being ignored as too common, lol), but if anyone else is curious I very clearly remember one post in said thread containing both of Guam's converters

It's probably been found before, but I was just playing around and noticed this. I was particularly bugged because I couldn't clean the second beehive.

Less weird than you'd think:

Still, that's an unsatisfying answer because the other beehive still can't be cleaned up.
