(6)r7c4=(6-9)r9c5=(9-4)r8c6=(4-6)r3c6=(6)r5c6 => r45c4<>6 |

Dan, I tried this puzzle and couldn't do a thing with it. As usual, I can't follow the notation and don't see where r9c5 enters into the equation. However, I can see if r7c4<>6, then r8c6=9 which forces r5c6=6, making the eliminations shown. |
