This is pretty much just a trackless instruction solve that has track because it's the best way to move a brick like this. I think it's pretty good, but it's also the most obvious way to do it I think (converting a 7 atoms/molecule into 4 by rotating a brick, and it's probably not insanely optimized for that solution space, not to mention other solution spaces that I didn't even consider. Then again, last time I submitted for instructions I also had no faith in myself and got 5th so who knows
