i have this problem:
you have six identical counters, and a 4x5 square grid. no more than one counter may occupy each square in the grid. How many different ways can you arrange the 6 counters onto the grid so that each row and columb contains an even number of counters?
Rotations and reflections that look different as you draw them on a fixed grid should be counted as distinct ways.

One obervation is that you've one blank row and two blank columns for each "primitive" solution. Can this be used to generate a set of solutions for each primitive?
