FORMULA
Empirical for column k:
k=1: a(n) = 2*a(n-1) -a(n-3)
k=2: a(n) = 4*a(n-1) -2*a(n-2) -6*a(n-3) +4*a(n-4) +2*a(n-5) -a(n-6)
k=3: [order 16]
k=4: [order 80]
Empirical for row n:
n=1: a(n) = a(n-1) +2*a(n-2) -2*a(n-3)
n=2: a(n) = a(n-1) +6*a(n-2) -6*a(n-3) -8*a(n-4) +8*a(n-5)
n=3: a(n) = a(n-1) +14*a(n-2) -14*a(n-3) -56*a(n-4) +56*a(n-5) +64*a(n-6) -64*a(n-7)
n=4: [order 21]
n=5: [order 96]
