FORMULA
Empirical for column k:
k=1: a(n) = a(n-1)
k=2: [order 12]
k=3: [order 18]
k=4: [order 24]
k=5: [order 63]
k=6: [order 81]
Empirical for row n:
n=1: a(n) = 3*a(n-1) -2*a(n-3) -6*a(n-4) +4*a(n-6) +6*a(n-7) +3*a(n-8) +a(n-9)
n=2: [order 9]
n=3: [order 18]
n=4: [order 24] for n>26
n=5: [order 63]
n=6: [order 96]
