Modular Whispers

Rules:

Normal sudoku rules apply. Digits separated by knight's move can't be the same. Adjacent digits on the line must differ by at least 5. Furthermore, for each three consecutive digits on the line should be exactly one from each of the set [1,4,7], [2,5,8], [3,6,9]. Each corner of the grid (means r1c1, r1c9, r9c1 and r9c9) can't add up to 13 with any of their orthogonally adjacent digits.

This puzzle was created for this month on monthly-puzzle-prompt on CTC discord. Where the rules were to make a puzzle with unusual combination of rules.
