Dan,
I assume this is your grid after the xyz-wing on {5,7,8} ?
if so, I don't see the w-wing {2,7}... unless you used another 578 xyz-wing I didn't see.
or maybe the w-wing was extended.
| Code: | .------------------.------------------.------------------.
| 8 5 6 | 2 4 7 | 139 139 13 |
| 9 2 3 | 1 5 8 | 4 6 7 |
| 4 7 1 | 3 9 6 | 5 8 2 |
:------------------+------------------+------------------:
| 2 3 58 | 578 78 1 | 9 4 6 |
| 7 6 4 | 9 3 *25 |*12 *125 8 |
| 1 9 58 | 6 28 4 | 7 *235 35 |
:------------------+------------------+------------------:
| 5 18 9 | 78 1278 3 | 6 *27 4 |
| 6 18 27 | 4 1278 9 | 28 35 35 |
| 3 4 *27 | 578 6 *25 | 128 12-7 9 |
'------------------'------------------'------------------' |
the extended, convoluted w-wing would be marked above.
(7=2)r7c8 - (2)r56c8 = (2)r5c7 - (2)r5c6 = (2)r9c6 - (2=7)r9c3; r9c8 <> 7 |

Norm,
Thanks for keeping me straight.  I omitted an x-wing on 2 r67c58
You got to the same place with your convolution. I like it.  |

I think I also had a convoluted solution, but it was the entire sequence of eight simple steps. In fact my first step was a x-wing 2 in r67c58 and step 7 was a xyz-wing on 578, so maybe steps two through six were not even required to solve the puzzle.

| I used the 578 XYZ-Wing, two Type 4 URs on 18 and 35, and an XY-Chain. |
