I didn't see either of the other two posts earlier otherwise I would have used them instead of the same cells but a more complex pattern..........
Quote: | AXY-wing -246 vertex (46)r6c5, Pincers (26)r4c4 & (24)r6c3 with fin (15)r6c3
If xy-wing is true: r6c4<>2
If fin is true: subset (125)r6c123; r6c4<>2
x-wing (7)r18c38; r37c7<>7 |
