I'm not sure I follow here. Where are the extra two neighbors that only you
see? I'm seeing one neighbor nw, one ne, one east, one se, one sw and finally
one to the west. There are no north and south neighbors. Where do you get a
total of eight? Take in the above example, the hex with 1,1 in it. I'm seeing
neighbors being: [0,1],[0,2],[1,2],[2,1],[2,0] and finally, [1,0]. I'm curious
now as to the additional two hidden neighbors.
