well, shrunk that p1815... I did find another still life that allows the output glider to be on a transparent lane, and here that means 1 row and column less:

Well, I did dig up these for this forum I guess: (from Posted by H. Koenig‏‎ on March 19, 2005. , but I added block trail stabilators and combined a few)

I managed to complete it into a Lx103, though the output clearance isn't great (though it still fits with SW-2 to make a H-to-G3 of SW1T202, as shown in the RLE):

I highly suggest adding other common conduit objects, especially the staircase hexamino, aka LoM.


I am kind of leaning towards not introducing that octomino or proscrastinator;, however, if some conduits are indeed "welds" of conduits that happens to have these "as bottleneck", I would rattler ...
