Fun puzzle - felt there should be a huge fish move on 5 somewhere - but in the end played these two steps...
Quote: | x-wing(5) ; r4c6<>5, r58c1<>5
m-wing(57) (7=5)r8c3 - r7c1=(5-7)r7c6=r7c78 ; r8c7<>7 |

Not huge, but the finned X-Wing in c24 might have been helpful if you hadn't found your second move. |

Danny, I did see the grouped kite r4/c4 - which does the same damage I think - plus some grouped transports. But it never took out one of the bilocal 5s as I was hoping for.. |

All of the bilocals contribute to a stable cycle after all fish eliminations. Some puzzles just don't want to cooperate! _ _
Code: | stable cycle (*)

UR 47 boxes36; r89c9<>47
X-Wing (5)
UR 14 boxes39; each solution solves box 1
