(4=6)r3c7 - (6)r3c1 = (6-5)r5c1 = (5-4)r5c5 = (4)r4c5 => -4 r4c7; stte
Also, something a bit uncommon:
After eliminating 79 from r3c6 in the type 1 UR r37c56, one gets
- Code: Select all
3 *48 5 | 6 1 *7 | 2 9 48

Now there is an "avoidable rectangle" at r13c26 => -8 r2c2; stte
Not sure if this is same as RSW's above
