EDIT: The P64 thunderbird hassler "can" support the glider push reaction, if it weren't for the fact that the glider would have interacted with the spark two generations earlier, and that there seems to be no domino sparker that can support it without being destroyed by the glider.

Is there any way to synthesize that loaf-like pattern?
A boat is also a one-glider seed for block-and-glider; you can just remove one cell from the ship, but you have to move the glider over by one lane.
And something that I just noticed this morning is that that boat+glider --> block-and-glider can be triggered by gliders coming from two different directions:

There has already been work on this in the periodic conduits thread.

Look at generation 37 of your pattern. Otismo's pattern appears to have removed objects that are not necessary for the LWSS's creation. However, doing that causes the LWSS to crash into a century instead of escaping, so otismo had to add other objects in order to suppress the junk that would have been suppressed by the objects that otismo removed.

The blinker from the Beethoven does not appear to be cleanable, though, because there's a cell that interferes with the spot where you'd normally place a fishhook. Interesting, though.

Use a T-nosed P4 or something like that with a blinker-deleting spark. I think 230P8 would fit there.

Yes, but people typically prefer stable catalysts. Sparkers can be useful, but conduits that work at any generation instead of only every 30th step or so are typically preferred (although in this particular case, the exact timing of deleting the blinker doesn't matter).

A pentadecathalon will probably do, if it fits. 15 is relatively prime with 2, so it has to delete the blinker eventually. I think it would delete the blinker before the conduit could be used again either way.

Unfortunately, the blinker interacts with the pentadecathlon one generation too early.
The side spark of a pentadecathlon does not fit. By moving the non-transparent block down one cell, though, a fumarole (p5; coprime to p2) can be made to work:

I don't know if slparse knows how to make a fumarole, but it should be doable. Taming of the rest of the pattern may come tonight, and hopefully it can move out of Useless Discoveries.

Not necessarily useless; it might be possible to use it as part of a P5n mechanism (e.g. like some kind of pre-pulsar shuttle or traffic jam) to remove one side of a forming traffic light. I know there are already some mechanisms that will do that, but it's possible that this might fill a niche somewhere.
