H Wing: (2=3) r7c9 - r4c9 = (3-1) r6c8 = r7c8 => r7c8 <2>

Leren (and others), the practice of keeping the candidate list in a cell in ascending order and inserting a '-' sign in front of each eliminated candidate would take up unnecessary space when there is more than one elimination in a cell. The customary method has been to move any eliminated candidates to the end of the list preceded by a single '-' sign.

I know I'm a pain on such matters, but when readers have to adjust to different representations of the same thing, at best it slows them down, and at worst it leads to misunderstandings when they jump the wrong way.

Still another view of the same general logic......

2r4c7=2r4c9-(2=3)r7c9-(3=6)r8c8-(6=4=2)r31c8 => r2c7<>2

and

ANP(17=4)r5c13-r1c3=(4=6=3)r138c8-(3=18)r6c87 => r5c7<>1

More complicated than the above solutions. Start with a Kite on 4 emanating from box 1, then extend it in stack 3.

Hope the notation's OK, at least one of them, lest I incur Ted's wrath. :lol:

4r4c1=r3c2-r1c3=r1c8-(4=6)r3c8-(2368=1)r7896c8-(1=4)r5c7=>r4c7<>4

-or-

4r4c2=r3c2=r1c3-(4=2)-(2r7c8=1r6c8)-(1=4)r5c7=>r4c7<>4
