Normal sudoku rules apply.
In this puzzle every digit conforms to an anti-king and/or anti-knight constraint. Identical digits share the same constraint/s and each digit must share at least one constraint with all of its factors. (eg. 9 must share a constraint with 1 and 3).
Adjacent digits on green whisper lines must differ by at least 5.
Solution code: column 6
