Hi

I need an example of a Hidden triple, where the triple is distributed as 3 x 2 candidates: xy,xz,yz

I have searched all the benchmark lists, but can't find one.
It doesn't matter what type of house.

Can anybody help me?

This puzzle is from Mike Barker's zoo contributions at www.sudoku.com/boards . I believe column five contains your desired pattern.

Code:
 *-----------------------*
 | 7 . 6 | . . . | . . . |
 | . . . | . 1 . | 5 . . |
 | 2 . . | 3 . . | . . 4 |
 |-------+-------+-------|
 | 6 . 9 | 7 . . | 3 . . |
 | . . . | . . . | . . . |
 | . . 3 | 4 . 9 | 8 . . |
 |-------+-------+-------|
 | . . . | . . . | . 2 . |
 | . . . | 6 5 8 | . . 3 |
 | 5 4 . | 9 . . | . 1 . |
 *-----------------------*

Code:
 *--------------------------------------------------------------------*
 | 7      1359   6      | 58     489    45     | 12     389    129    |
 | 8      39     4      | 2      1      67     | 5      369    679    |
 | 2      159    15     | 3      6789   567    | 17     689    4      |
 |----------------------+----------------------+----------------------|
 | 6      258    9      | 7      28     125    | 3      4      12     |
 | 4      2578   25     | 58     2368   12356  | 127    569    12679  |
 | 1      257    3      | 4      26     9      | 8      56     267    |
 |----------------------+----------------------+----------------------|
 | 3      6      8      | 1      47     47     | 9      2      5      |

Thanks a lot daj95376.

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.
