				| Thanks for the puzzle immp! 
 After basics:
 
  	  | Code: |  	  | +--------------+--------------+----------------+ |  46  34  2   | 9   5    67  |  17  3478 1348 |
 | d569 1   39  | 8   4   e67  | f57  2    35   |
 |  8   45  7   | 2   1    3   |  569 469  4569 |
 +--------------+--------------+----------------+
 |  2   357 1   | 567 9    4   |  8   36   356  |
 | c59  8   39  | 56  2    1   |  4   369  7    |
 | b579 6   4   | 57  3    8   | a59  1    2    |
 +--------------+--------------+----------------+
 |  17  2   5   | 4   678  9   |  3   678  168  |
 |  147 9   8   | 3   67   2   |  167 5    146  |
 |  3   47  6   | 1   78   5   |  2   4789 489  |
 +--------------+--------------+----------------+
 | 
 Then I used the chain: (5-9)r6c7=r6c1-(9=5)r5c1-(59=6)r2c1-(6=7)r2c6-(7=5)r2c7 contradiction => r6c7 <> 5; stte.
