Use of Diagrams
In the following I’ll use diagrams showing all six faces at once.
The diagrams will always be paired. The left part shows in 3D fashion the faces U,R.F and the right part a view of the other three faces B, L and D.
It may be a bit hard to imagine individual cubies on a scrambled cube, if some stickers are hidden.
After a while you will become used to these diagrams, though.
Very often, it is sufficient to look at the left part, but if we want to know which stickers can be viewed e.g. on the L wall, we have to look at the right part.
Each sticker is in one of the faces and carries the name of that face
Very often I’ll call the U layer the “roof” and the D layer the cellar
and the vertical layers are “walls”
The 8 corners have 3 stickers each; only two of them are completely visible on one part of the diagram: UFR and LBD
Each corner is named by using 3 letters, the layer names.
When I use a corner position name like UFR , I mean the corner cubie currently at that place (the order of the 3 letters doesn’t really matter)
The 12 edges; only 6 of them are completely visible on one part of the diagram(UF, UR, FR; BL, BD, LD); the arrows indicate which stickers are on the edge cubies; Each edge is named by using 2 letters, the layer names.
When I use in the later text an edge position name like UF , I mean the corner cubie currently at that place (the order of the 2 letters doesn’t really matter)
I show all possible turns done on a solved Rubik’s Cube:
