FORMULA
Empirical for column k:
k=1: a(n) = 2*a(n-1)
k=2: a(n) = 3*a(n-1) -a(n-2)
k=3: a(n) = a(n-1) +6*a(n-2) +2*a(n-3)
k=4: a(n) = a(n-1) +12*a(n-2) -2*a(n-3) -38*a(n-4) +a(n-5) +12*a(n-6) -a(n-8)
k=5: [order 7] for n>9
k=6: [order 32] for n>33
k=7: [order 52] for n>54
Empirical for row n:
n=1: a(n) = a(n-1) +a(n-2)
n=2: a(n) = 2*a(n-1) +a(n-3) -a(n-4) -2*a(n-6) +a(n-7)
n=3: [order 24] for n>25
