How to recognise it
Only the left and right edges are yellow on top, with headlights on both the left and right sides.
Its inverse is another case
Do the 56 algorithm backwards, r' U' r R' U' R U R' U' R U r' U r, and you are solving 53.
That's why CubeDojo never scrambles 56 that way: it builds a random state with the case fixed, so you practise 56 and not 53.
