8r46c3=(8-5)r5c2=(5-3)r5c6=(3-8)r4c6=8r4c3 => r8c3<>8
Another solution using the same logic is an ASdC(12567)r789c1 with (12)r4c1 and (56=8)r8c3 => r3c1<>2, r7c3<>6, r3c1,r7c3<>7

[8r8c3-8r46c3=(8-5)r5c2=(5-3)r5c6=(3-8)r4c6=8r4c3 Conflict => r8c3<>8] thus SdC is true => r3c1<>2, r7c3<>6, r3c1,r7c3<>7
