FORMULA
Empirical for column k:
k=2: a(n) = 5*a(n-1) +6*a(n-2) +8*a(n-3) +3*a(n-4) -8*a(n-5) -5*a(n-6)
k=3: [order 9]
k=4: [order 32]
k=5: [order 81]
Empirical for row n:
n=1: a(n) = 2*a(n-1) +a(n-3)
n=2: a(n) = 6*a(n-1) +4*a(n-2) +25*a(n-3) +60*a(n-4) -24*a(n-5) -72*a(n-6)
n=3: [order 19]
n=4: [order 58]
