Each main diagonal cannot contain a repeated digit.

Clues outside the grid are sandwich clues, but there are THREE crust digits (to be identified by the solver), and the clue indicates the combined sum of all three available sandwiches.

For example, if the crust digits are 2,5,8, then the sandwich sum for the row 123456789 would be:

(3+4) + (6+7) + (3+4+5+6+7)
= 7 + 13 + 25
= 45
