Does this qualify as a Sashimi X-Wing? (There is an extra 1 in c4, so no Skyscraper). Either r5c4 or r7c56 must=1, precluding a 1 in r8c4.
Yes, there's a Sashimi X-Wing. The vertex cells are marked with (*) and the fin cells are marked with (#).
Thanks Danny, you always seem to be there when a question needs answering.
I just did a puzzle with a good example, so I thought I'd post it.
Note the 4s in r34. It would be a conventional Skyscraper if either r4c1 or r4c3 did not contain a 4. With both 4s present it becomes a Sashimi. Either r3c2 or one of r4c13 must be a 4; whichever, r5c2<>4.

Hmm, don't recall ever hearing of a sashimi skyscraper. Grouped skyscraper should be good enough IMO.
My wording wasn't very good. I meant that with two 4s it becomes a Sashimi X-Wing.
