Chess probability challenge

Here is my challenge to all . Try to make a program that will give us the no. of ways to place n queens on a n*n chess board such that no queen threatens the other . For eg: to place 4 queens on a 4*4 chess board we have only 2 ways 1. 2. 3. 4. 1. q 2. q 3. q 4. q and other one it's reflection. Good luck and Happy programming !
