On a Grid (Posted on 2007-08-08)

Place eight 'A's and eight 'B's in a 4x4 grid such that each 'A' is orthogonally bordered by 1 or 3 'A's and each 'B' is orthogonally bordered by 0, 2, or 4 'B's.

Can a 6x6 grid be filled with 18 'A's and 18 'B's in this manner?

Note: 'orthogonally' means horizontally or vertically
