How to recognise it
A C shape: the left and right edges with the two front corners. The back corners' yellow faces left and right.
Its inverse is another case
Do the 34 algorithm backwards, F U R' U' R' F' R U R2 U' R', and you are solving 37.
That's why CubeDojo never scrambles 34 that way: it builds a random state with the case fixed, so you practise 34 and not 37.
