Our logo shows a solution to the famous eight queens problem:

 

How do you place eight queens on a chessboard so that none can capture any other?

 

To arrive at this solution you can compute:

 

(2⁸ - 1) / (8 - 1) which equals 255 / 7 which equals (rounded to 6 decimals) 36.428571

 

The eight digits making up that number are the numbers of the rows in which to place 8 successive queens.
