Apparently folks have fixated on a particular algorithm in the wikipedia article. I only linked there for a general description of the problem. Instead, I should have simply said, "write a program that produces all the solutions to the problem of placing 8 queens on a chess board so that no queen is attacking any other queen and prints the solutions as follows (i.e. the output in the OP)"
I'm not too excited about an algorithm that only finds one solution, although it is clever.
