I swear I'll post something else than disjoint + LK + palindrome next time
Rules:
Normal sudoku rules apply.
Little killer sum rules apply: the numbers along the indicated diagonal must sum to the given total. Digits may repeat along the diagonal.
Palindrome rules apply: lines on the grid read the same in both directions.
Disjoint group rules apply: no two cells in the same position relative to their box (e.g. R1C1 and R4C4) may contain the same digit.

Solution code: Row 3, Column 6

WOW! thank you for this great puzzle, one of the hardest sudoku I've ever solved.
I am glad that Simon featured Lake Trip puzzle a couple of days ago in his channel so I get to know about you.

I'm so pleased CtC featured one of your puzzles recently as it tempted me to have a look at the others. All I can say is wow! Incredibly tight logic and stunning! Very difficult but so rewarding - thanks :)

I didn't expect this puzzle to be '2nd solve after 20+ days' levels of hard, but clearly I was wrong :P Glad you liked it PixelPlucker :)

This is the hardest sudoku I've solved in a very long time! It was beautiful, though.
