FORMULA
Empirical for column k:
k=1: a(n) = 2*a(n-1)
k=2: a(n) = 2*a(n-1) -a(n-3) for n>4
k=3: a(n) = 2*a(n-1) -a(n-3) for n>6
k=4: [order 15] for n>16
k=5: [order 24] for n>28
Empirical for row n:
n=1: a(n) = a(n-1) +a(n-2) for n>3
n=2: a(n) = 3*a(n-1) +a(n-2) -6*a(n-3) -2*a(n-4) +4*a(n-5)
n=3: [order 20] for n>21
n=4: [order 72] for n>73
