Disjoint Sets, Kropki, Palindrome Sudoku

Rules:

Normal Sudoku rules apply.

Additionally, disjoint groups apply. Each position within each box contains one of each digit 1-9. For instance, {R1C1, R1C4, R1C7, R4C1, R4C4, R4C7, R7C1, R7C4, R7C7} form a disjoint group.

Digits on gray lines form a palindrome, that is, the sequence of digits is the same from either end.

Kropki Sudoku rules apply. Digits connected by a white dot are consecutive. Digits connected by a black dot have a ratio of 2:1. Not all dots are given.
