For N=4, each solution has exactly 4 non-attacking queens on the board (as you correctly said, the number of queens equals the board size N). What I meant by '8 queens' is the total number of queens across all solutions. Since N=4 has 2 solutions, I was imagining placing each solution on a...

N-Queens: Total Queen Count Patterns I've been studying N-Queens solutions and noticed something about the total number of queens across all solutions. For example, N=4 has 2 solutions. Total queens = 2 × 4 = 8. This is like preparing 2 separate 4×4 boards and placing one solution pattern on...
