Ted, I'm not gonna argue, just say that I learned that pattern as a Sashimi and that's what I'd still call it. Smile

However, it may be that Sashimi and Finned Skyscraper are one and the same.

Same elimination as tranglet using a chain
(7=4)r1c9-(4=1)r1c6-(1=8)r1c3-r2c1=r4c1-r4c89=r5c8-r9c8=(8)r8c9 => -7r8c9; stte

I've never understood the notation. Does any of this mean that:
r9c4<>7 because if it were r1c4<>7 - r1c9=7 - r8c9<>7. Therefore
one of r9c78 would have to provide the 7 in box9. Since that's impossible
r9c4 must =8 stte. ?
