- The puzzle requires placing 4 salamanders on a 5x5 grid so that no two are in the same row, column, or diagonal.
- This is analogous to the classic "N-Queens" problem, where the goal is to place N queens on an N×N chessboard without them attacking each other.
- For a 5x5 grid, there are multiple valid solutions; the image displays two of them.
- In the first solution, the salamanders are placed at positions: (1,1), (2,4), (3,2), (4,5), (5,3) — using (row, column) notation starting from 1.
- In the second solution, the salamanders are placed at positions: (1,1), (2,3), (3,5), (4,2), (5,4).
- Both arrangements satisfy the constraint: each salamander occupies a unique row and column, and no two share a diagonal.
