EG-2

Solve a 2x2 whose first face has a diagonal corner swap underneath: 40 cases.

What it is

EG-2 is EG for a first face with a diagonal swap underneath. Together with CLL and EG-1 it lets a solver skip building the first layer's permutation.

Recognition

Headlights on all four sides of the bottom layer: solved (CLL). Headlights on exactly one side of the bottom layer: adjacent swap (EG-1). No headlights on the bottom layer: diagonal swap (EG-2). Then read the top as for CLL.
