T(n,k)=) = Unmatched value maps: number of nXk binary arrays indicating the locations of corresponding elements not equal to any horizontal, vertical or antidiagonal neighbor in a random 0..1 nXk array.

| FORMULA
|
Zeilberger's Maple code (see links in A228285) would presumably give recurrences for the columns of this array. - . - _N. J. A. Sloane, _, Aug 22 2013

Column 1 is A005251(n+2)).
Column 2 is A002478(n+1)).
Column 3 is A105262(n+1) for n>1.
