I also found the AUR(19) so I looked for another solution and found this
anp(17=8)r4c3+r5c1-(8=4)r5c6-(4=3)r8c6-(3=2)r8c2-r8c3=r6c3; r6c3<>7

Ted, I must be in an overly technical mood this morning, but the 19 is a UR (Type 4), not an AUR. But I would say that it's an ADP. |

Marty,
In hindsight, I agree that it is a Type 4. However I initially view all such patterns as UARs. In this case, I looked at the external strong inferences and found only one: r3c7=9. Thus I solved the puzzle as an AUR and posted that solution.
