Hard to remind everything, so I detail JE processing:

Double JE4: (2345)r2c12, r1c5, r3c7; (2345)r3c46, r1c3, r2c7
Double JE with three cross-lines => all base digits are true in base and target cells of one or the other JE
First eliminations:
- non-base digits in target cells: -8 r1c5, -9 r3c7, -9 r1c3, -8 r2c7
- base digit false in mirror cells: -25 r1c3
- base digits in cells seeing all 4 base cells or all 4 target cells: -2345 r2c5, r3c3, r1c89; lcls, 6 placements
- Code: Select all
