@Reza: I think he reworded it. As for how to solve it, I didn't find a formula or anything. I just basically used his 5x5 example and extrapolated it. It's much less complex than you think it'll be.

@Seth Cohen: Thanks Seth, I solved it by looking at the 5×5 picture and thinking harder. Thanks to Matthew for another enjoyable set of puzzles. I look forward to reading the proper solution.
