# Question about reflection, eight queens problem. [closed]

When I am to reflect a current chessboard around say the horizontal line Y=4, would that imply that I need to reflect the bottom part to the top part, and then the top part to the bottom part?

What does this have to do with the eight queens problem? – Gerry Myerson Sep 10 '11 at 12:27
There are 92 solutions, only 12 unique if you those that differ only in rotation or reflection. – Algific Sep 10 '11 at 18:55
@Gerry: It looks like part of set of exercises involving counting the number of distinct solutions to the eight queens problem modulo one or more sets of symmetries. – Brian M. Scott Sep 10 '11 at 19:33
