Borders with black dots separate regions with neither the same size nor the same orientation. Borders with grey dots separate regions with either the same size or the same orientation, but not both. The grid is toroidal, that is regions are allowed to extend past the edge of the grid to reenter on the other side.  (Technicality: There are two edges given on the side of the grid. For aesthetic...
