OLL 47
The algorithm, how to recognise it and how to practise it without cheating.
Recommended algorithm
R' U' R' F R F' R' F R F' U R12 moves
Alternatives
F' L' U' L U L' U' L U F10 moves · with the left hand
How to recognise it
Only the back and right edges are yellow on top. Headlights on the right, and the front-left corner's yellow faces you.
Its inverse is another case
Do the 47 algorithm backwards, R' U' F R' F' R F R' F' R U R, and you are solving 52.
That's why CubeDojo never scrambles 47 that way: it builds a random state with the case fixed, so you practise 47 and not 52.
