| An xy-wing 157 solves it in one step. |

| There are three 157 xy-wings; any one is a single stepper. There is also a type 1 UR on 38, but it still needs the help of a 157 xy-wing to solve. As for the 139 xy-wing, I can't find the necessary 13 cell anywhere on the grid after basics. Give me some help on that one kdelle. |

| A W-Wing on 17 also does it. I can't find a 139 XY-Wing either. |

The 13 was in Box 1, but when I tried to reconstruct it, that cell was solved for 1. I must have made a mistake, because all I see the second time through are athe 157s. Oops! |

| Went the 38 UR route since I spotted it first, but still needed the 157 XY wing. |
