M-Wing. R5c1=7 proves r1c3=7. R1c3<>1 proves r7c3=1; r7c1<>1. I suppose it can also be expressed as an AIC without calling it an M-Wing.

Code:

+--------------+---------+---------------+
| 147 134 1347 | 8  9  2 | 6    5    34  |
| 289 29  5    | 3  4  6 | 27   1    278 |
| 28  6   34   | 5  7  1 | 34   9    28  |
+--------------+---------+---------------+
| 3   49  8    | 1  6  7 | 249  24   5   |
| 17  15  2    | 9  35 4 | 8    367  67  |
| 6   459 479  | 2  35 8 | 3479 347  1   |
+--------------+---------+---------------+
| 149 8   1349 | 46 2  5 | 347  3467 679 |
| 5   7   49   | 46 8  3 | 1    246  269 |
| 24  234 6    | 7  1  9 | 5    8    34  |
+--------------+---------+---------------+
