R2C1 - removing <1> from <123> leaving <23>

R3C2 - removing <1> from <1258> leaving <258>

Intersection of column 7 with block 9. The values <257> only appears in one or more of squares R7C7, R8C7 and R9C7 of column 7. These squares are the ones that intersect with block 9. Thus, the other (non-intersecting) squares of block 9 cannot contain these values.
