Standard palindrome, nonconsecutive, inequality sudoku rules apply. That is:
1) Normal Sudoku rules apply.
2) Grey lines are PALINDROMES, which read the same forward and backward.
3) INEQUALITY signs point to the smaller of the two cells (e.g., r5c2 is larger than r5c3).
4) Orthogonally adjacent cells MAY NOT contain CONSECUTIVE digits.
