X3
PLL
X - No blocks or headlights
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: R2 U R' U' R2' U' R U' R' U2 R U' R U2 R' U' R2 U' R2' y2. Every algorithm above was run by our logic engine from that state and reaches "pll-solved", keeping first-layers and oll-solved.
