When I run this via (nqueens 8), I only get one output:

  arc> (nqueens 8)
  (2 4 6 8 3 1 7 5)  
  arc>
There should be 92 solutions displayed.

This algorithm only finds one correct solution for each n.

The wikipedia algorithm only generates one solution.

The challenge is to produce all 92 solutions as the Ruby code does in the OP. I linked to wikipedia for the description of the problem, not the algorithm.

I also showed the ellided output for clarification.

I was doing the n queens challenge on Wikipedia because someone had already posted a solution to your challenge.
