FORMULA
Empirical for column k:
k=1: a(n) = 3*a(n-1) +a(n-2) -2*a(n-3)
k=2: a(n) = 5*a(n-1) -2*a(n-2) -5*a(n-3) +2*a(n-4)
k=3: [order 10]
k=4: [order 16]
k=5: [order 36]
k=6: [order 62]
Empirical for row n:
n=1: a(n) = 4*a(n-1) -5*a(n-2) +2*a(n-3)
n=2: a(n) = 6*a(n-1) -14*a(n-2) +16*a(n-3) -9*a(n-4) +2*a(n-5)
n=3: [order 8]
n=4: [order 10]
n=5: [order 12]
n=6: [order 14]
n=7: [order 16]
