589 triple in c6=> -8r6c5

I missed the wing. For those of us who Iike to limit ourselves to the standard X-, XY- and XYZ-Wings, this one's a shame. There's a very nice Sashimi (aka Grouped Skyscraper) on 7 in c24=> -7r6c5, which I think solves it.

Hey Marty, the 47 pair in column 6 also removes the 8 from r5c6! Laughing

There is also a hidden 159 triple in c5 that lets you set 3r5c5, but you still need an X wing on 6 or Clement's wing or another XY of 46-7 pivoted in r4c5 to solve it.
I would not have posted this, but I'm really bad at triples, especially hidden ones, so when I do find a hidden one, I just have to tell somebody.

The 1 in r4c5 destroys the 159 would be triple. If 1 was not in r4c5, it would have been a triple.
