jpf will surely recognize this diminished version of a well-known pattern:

Code: Select all

 . 6 . . . . . . 8
 . . 1 . 2 . . 3 .
 . . . 7 . . 5 . .
 . . 3 . 1 9 . . .
 . . . . 5 4 . 2 .
 . . . 8 . . 6 . .
 . . 9 . . 3 . 1 .
 . 8 . . . . . . 7
 . . . . . . . . .  SE 9.0, 9.0 Pearl, minimal, 20 clues,
                    symmetric about the 8x8 diagonal and anti-diagonal

Once again, there are striking symmetries also in the values.
