This can be reduced to 12 by building the stilllifes simultaneously. This could previously be done from 11 gliders (my web page currently says 12, but most blockerbased oscillators were improved by 1 by Bob Shemyakin's 5glider blocker synthesis from no later than 2015):

I can't find the object in jslife, and it's certainly not in Dean Hickerson's oscillator collection

Can anyone find a way to improve its cleanup?
Also for a name, maybe something to do with "slowing lump of muck" (as part of it looks like one of the stages for lumps of muck)?

That's a stator variant of the

Nice. Actually, it's only 14 gliders, and cleanup can be done with 3 gliders instead of 4, reducing it to 13. (It might also be possible with 2 if you look hard enough):

If you advance that a bit, the predecessor becomes even simpler. Here it is from 10 gliders. (9 might be possible; many positions of the cleanup glider leave the beehive+blinker combination, and some leave 12 other objects. It's possible one might leave nothing, of you try an exhaustive search). As a bonus, all gliders approach from only 2 directions, which might make constructing a 4snark gliderloop easier.

@ mniemiec The big finding is that it's now possible to use in slow salvo construction for self constructing circuitry.
Any idea how to end the snark using SL seeds?

I meant that one could use gencols or similar to find a small glidertriggered constellation that produces a block at the edge of its reaction envelope.
