How can i build the shape --Ru----:Ru--RuRu ?

Empty corners required to associate low layer and higher layer quadrants, so how to resolve 3 quadrants on the same higher layer 🤔
Looks like there is a rule like "if the top layer has more than 2 quadrants above nothing and there is no superposition, then the shape is infeasible"
