# So many numbers

Consider the above 8$$\times$$8 grid. How many ways are there to write a single digit (0, 1, ..., 8, 9) in each square such that the sum of all the numbers in any 3$$\times$$3 section is even. If you think the number of ways to fill in this grid with these restrictions is $$x$$, type in the number of factors of $$x$$ (including 1 and $$x$$).

Note: Rotations and reflections are considered to be distinct possibilities.
