### Stuck on some puzzle from some variant

I have classical sudoku and four additional constraint groups for 1-9:

Code: Select all
`...|...|......|...|.....X|...|X..---|---|---...|...|......|X.X|......|...|...---|---|---...|.X.|......|X.X|.....X|...|X....X|...|X.....|X.X|......|.X.|...---|---|---...|...|......|X.X|......|...|...---|---|---..X|...|X.....|...|......|...|......|...|......|...|...X..|...|X..---|---|---.X.|.X.|.....X|...|....X.|.X.|...---|---|---X..|...|X.....|...|......|...|......|...|......|...|.....X|...|..X---|---|---...|.X.|.X....|...|X.....|.X.|.X.---|---|---..X|...|..X...|...|......|...|...`

Then the following puzzle and my current stage:

Code: Select all
`.49|...|.....2|..6|.9....|...|...---|---|---2..|...|..4..3|...|..1...|3..|...---|---|---..1|8..|......|...|5.....|...|...+-----------------------+-----------------------+-----------------------+|(3678)    4       9    |(1257)  (12578) (1257) |(378)   (3678)  (25678)||(378)     1       2    |  4     (3578)    6    |(378)     9     (578)  ||(5678)  (357)   (678)  |(279)   (378)   (23789)|  1       4     (2678) |+-----------------------+-----------------------+-----------------------+|  2     (6789)  (578)  |(1679)  (6789)  (1789) |(36789) (3578)    4    ||  4     (6789)    3    |(57)    (26789) (578)  |(6789)  (278)     1    ||  1     (6789)  (578)  |  3       4     (2789) |(6789)  (2578)  (78)   |+-----------------------+-----------------------+-----------------------+|(5679)  (357)     1    |  8     (39)    4      |  2     (67)    (3679) ||(36789) (378)     4    |(29)    (167)   (239)  |  5     (1678)  (36789)||(39)      2     (678)  |(1567)  (1567)  (157)  |  4     (1678)  (39)   |+-----------------------+-----------------------+-----------------------+`

How should I proceed?

There should be a pointing pair or n-tuple but I'm stuck.

I double-checked that my solver finds one single solution.

Nothing fancy needed - just fully play the extra groups.
