I used a Type 4 UR, AIC + transport and two XY-Wings. If someone should actually want the details, I have them. This is where I was after basics:

| 2 6 58 | 4 358 7 | 38 1 9 |
| 345 3589 1 | 2 3589 89 | 348 7 6 |
+--------------+--------------+---------------+
| 35 2358 7 | 1 248 28 | 6 9 45 |
| 1 258 258 | 89 2489 6 | 7 45 3 |
