Great work Extrementhusiast!

Here is the full synthesis in 24 and 28 gliders:

Your method will reduce many syntheses of Elkies P5 variants. It obsoletes the recently solved variant without a tub. Unfortunately your snake-to-eater converter doesn't work here because the tub gets in the way, which I haven't been able to work out how to fix.

Anyway, while I'm here, I added a lot more clearance to the ship-to-tripole converter:

Code: Select all

I also found a reduction to up beacon on up long bookend with tub which also acts as a converter:
