FORMULA
Empirical for column k:
k=1: a(n) = a(n-1)
k=2: a(n) = 2*a(n-1) +2*a(n-2) -a(n-3)
k=3: a(n) = a(n-1) +12*a(n-2) +5*a(n-3) -12*a(n-4) -2*a(n-5)
k=4: [order 15] for n>16
k=5: [order 17] for n>20
k=6: [order 72] for n>75
Empirical for row n:
n=1: a(n) = a(n-1) +a(n-3) +a(n-4)
n=2: [order 16] for n>19
n=3: [order 64] for n>68
