A one stepper:
Quote:
(3=7)r3c4-(7=8)r3c7-(8=6)r2c9-(6)r8c9=(6)r8c6-(6=3)r9c6
=> r23c6,r79c4<>3
The year is looking better. Very Happy

Another one step solution.

Quote:
(8=7)r3c7 - (7=3)r3c4 - (3)r79c4 = (3-6)r9c6 = (6)r8c6 - (6=8)r8c9; r2c9<>8.

Two steps, but I don't know if the first played a part in the solution.

Type 1 UR (26)
Type 4 UR (45)
