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' R2' U' R U2' R' U R U R' U 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.
