the AUR/DP type structure is in r56c147 on {2,4,7}
this means that the group of 5's in r56c1 and the 3 in r5c4 are strongly inferenced.
(5)r2c5 = (5)r2c1 - DP247[(5)r56c1 = (3)r5c4] - (3=5)r4c6;
r1c6 and r56c5 all not 5 |

| I used the same DP, but without inferences. Either r56c1=5 or r5c4=3. Common outcome; r1c6=6. |
