Thanks to Scojo for the inspiration for this puzzle! Happy solving!
Rules:
Normal sudoku rules apply. Place the digits 1 to 9 in each Row, Column, and 3X3 box.
Disjoint groups: Digits do not repeat in the same relative position with any box (e.g. R2C2 and R5C5 must be different).
Sandwich sums: Sandwich clues outside the grid indicate the sum of the digits between 1 and 9 in that row/column.
Difference dots: Digits in cells separated by a green dot must have a difference of 5.
Even: Cells with grey squares must contain an even digit.
Solution code: Row 9 digits from left to right.
