Fill as much of a 6x6 grid with the letters A, B, C, D, E, F so no two of the same letter are in the same row, column or diagonal.

It is impossible to entirely fill the grid, but what is the largest number of letters that may be placed?

Best I could accomplish so far is 32.

Charlie, you need to look at your code.  The 'f' in the bottom left corner is paired on the rising diagonal in each of your "solutions".
