I was thinking about a Quadruple/Anti-Knight combination for quite some time and eventually had a break in idea that felt worth concluding into a puzzle. Hope you enjoy the solve as much as I enjoyed setting.
Standard Sudoku rules apply
❶ Quadruple: each of the numbers in the white circles must appear in the four surrounding cells at least once.
❷ Anti-Knight: cells that are a knight's move apart in chess cannot contain the same digit
Solution code: Column 9

Quadruples and anti-knight fit very well together. Fun puzzle. :)
