Four shapes that fit no group, with longer algorithms.
Goal
Make the whole top yellow when you see one of the four awkward shapes.
How to recognize it
Two neighboring yellow edges and two yellow corners on one side, but not a P. Check the yellow stickers on the sides to pick the shape.
How to hold the cube
White face on the bottom, first two layers done. Each shape's grip is shown under the controls. Turn U to line the shape up.
The main idea
OLL 41 and 42 are a Sune (or Anti-Sune) joined with F R U R' U' F'. If you have not learned them, use 2-look OLL.
Check before moving on
The whole top is yellow, and the first two layers are still done.
