FORMULA
Empirical for column k:
k=2: a(n) = 2*a(n-1) +3*a(n-2) -2*a(n-3)
k=3: a(n) = 3*a(n-1) +19*a(n-2) +19*a(n-3) +12*a(n-4) -8*a(n-5) +8*a(n-6)
k=4: a(n) = 8*a(n-1) +33*a(n-2) -68*a(n-3)
k=5: [order 36]
k=6: [order 93]
Empirical for row n:
n=2: a(n) = 3*a(n-1) +8*a(n-3) +6*a(n-4) -4*a(n-5) for n>6
n=3: [order 10] for n>11
n=4: [order 31] for n>32
