Disappointed that I couldn't find a good pattern-based solution.
(7=9)r6c4-(9=1)r6c7-(126=9)r613c1-(9=7)r3c3=>r3c4<>7 |

Marty,
This may be "pattern based", but it's not pretty:
RNP 69
W -26
XY 67-9
XY -267
SS 6
SS 7
UR 26

Keith I agree. As you probably realized, I had in mind a pattern-based solution of fewer steps. |
