There is indeed a hidden triple: [4,7,9] in R1C5 & R3C5 & R7C5 which is in the right configuration. I HAD checked Mike Barkers Zoo, but I missed this one, because there also is a "regular" hidden triple: [1,2,3] in R4C6 & R5C6 & R9C6 (after singles), which leaves only singles, so my solver just finished the puzzle, before I ever saw this one. I have disabled the regular hidden triple search, and can now work on this special case. /tjacob Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         Sudoku Programmers Forum Index -> Puzzles All times are GMT Page 1 of 1   Jump to: Select a forum Sudoku----------------Solving sudokuSetting sudokuProgramming sudokuThe mathematics of sudokuExotic sudoku Library----------------PuzzlesSoftwareSudoku elsewhere Not sudoku----------------Random thoughtsForum feedback  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum   Powered by phpBB © 2001, 2005 phpBB Group Igloo Theme Version 1.0 :: Created By: Andrew Charron
