Presented to Édouard Lebeau on the occasion of his 50th birthday, November 2022.
Normal Sudoku rules apply.
Digits in cages must add to the indicated total. Repeats are not permitted in cages.
Digits along indicated diagonals must add to the indicated total. Repeats are permitted along such diagonals.
Each row, column, and 3x3 box contains exactly one 'negator' cell. Digits in these cells must be subtracted, rather than added, to achieve the given cage or diagonal totals. The nine 'negator' cells are also a set of the digits 1-9.
Solution code: Row 1, then column 5 (18 digits total)
