Adj Opp

PBL

Headlights on all four sides of a layer (read each layer on its own): solved. Headlights on exactly one side of a layer (read each layer on its own): adjacent swap ('Adj'). No headlights on a layer (read each layer on its own): diagonal swap ('Opp'). A case's name reads the top layer first, then the bottom.

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' F2 R F' R. Every algorithm above was run by our logic engine from that state and reaches "pll-solved", keeping faces.
