Standard killer Sudoku with the fewest clues

[Phistomefel]

Thank you for sharing this, cdwg2000! After watching the CtC video on the 18-cell killer sudoku I was naturally wondering whether it was possible to reduce the amount of cells covered by killer cages to 17. It is interesting to read that they were able to prove (by exhaustion) that this is not possible. Also it seems like the author "mith" who wrote the posts in the enjoysudoku forum is Philip Newman, the author of the 18-cell killer sudoku which came to be known as the Miracle Killer Sudoku.
