OCLL (2-look OLL, step 2)
The seven cases with the edges already oriented: the second look of 2-look OLL.
What it is
OLL is CFOP's third step: with the first two layers solved, one algorithm turns every last-layer piece so the top face shows one colour. Permutation does not matter yet; PLL comes next.
The 57 cases group by their shape on the top face: dot (no edges oriented), line, L-shapes ('lightning', 'fish', 'knight move', ...), and the seven OCLL cases where the edges already form a cross. Beginners use 2-look OLL: orient the edges (3 algs), then the corners (7 algs).
Recognition
Look at the top face first. Count the top-colour stickers on the top face's edges: none is a dot; two opposite is a line; two adjacent is a L; all four is a cross. That narrows it to a group; then the corner stickers on the top and the sides (headlights, bars) pick the case.
