alternatively, using DP (269) r1c78, r79c268: If r1c7 <> 4, r7c2 = 1
(4)r1c7 = (1)r7c2 - (1=2)r1c2 - (2=4)r2c1 => same

BUG+4 => at least one of 2 r1c1, r7c2, 6 r1c57 is True
2 r1c2 =BUG= 9 r1c8 - r7c8 = r9c7 - (9=2) r9c2 - 2 r1c2 => - 2 r1c2; stte
Simple !

How about:
26Bug:r1c57,r7c2-(6=2)r1c23 loop => -6r1c8

Doesn't look quite right. I can see (6) r1c57 =BUG= (2) r1c1, r7c2 - (2=6) r1c23 loop => - 6 r1c8
