Look at:
- If r1c8<>45 => [(9=6)r1c8-r1c45=(6-2)r3c5=r3c8] => r3c8<>9
- AAHS(56)r1369c5 * marked cells => (56)r13c5=(5)r6c5=(56)r9c502:
Present as diagram: =>
r3c8<>9,
stte- Code: Select all
AAHS(56)r1369c5
||
(56)r13c5-(2)r3c5=r3c8*
||
(56)r9c58-r9c1=(5)r8c1-(57=6)r8c69-(6=45)r69c8-(45)r1c8=[(9=6)r1c8-r1c45=(6-2)r3c5=r3c8]*
||
(5)r6c5-(5=23)r5c46-(23=468)r5c123-(46=9)r4c2-r4c6=r1c6-r1c1=r3c3*
Note: based on AAHS(56)r1369c5, one can eliminate 5r9c1 or 45r1c8… but the presenting is more complex.
Thanks for the puzzle!
