How to recognise it
A T shape: the right column and the left edge. The left corners' yellow faces front and back.
Its inverse is another case
Do the 33 algorithm backwards, F R' F' R U R U' R', and you are solving 37.
That's why CubeDojo never scrambles 33 that way: it builds a random state with the case fixed, so you practise 33 and not 37.
