Knight's Index
(Published on 2. January 2024, 02:03 by Scojo)
Rules:
- Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
- Anti-knight: Cells that are a chess knight's move apart may not contain the same digit.
- Column indexing: A cell in row R column C containing digit D indicates that the cell in row R column D contains digit C. For example, if row 4 column 2 contained the digit 3, then row 4 column 3 would contain the digit 2.

I love indexing puzzles (I know, I'm weird), and this is a fantastic one. Thank you for a fun puzzle!

Very interesting to see how the two constraints played into each other. Nice puzzle!
