Look for blocks (pairs and lines of matching stickers) on the sides; their kind and position name the group.

How this case is verified
The case is the source's setup (or, where it has none, another source algorithm reversed). Setup: R' U' R' U2' F' R U R U' R' F R' U2 R U R. Every algorithm above was run by our logic engine from that state and reaches "pll-solved", keeping first-layers and oll-solved.
The case is defined by its only listed algorithm (or the source's setup), so the engine confirms the algorithm solves the case drawn, but the case's name rests on the source alone.
