FORMULA
Empirical for column k:
k=1: a(n) = 2*a(n-1)
k=2: a(n) = 3*a(n-1) +a(n-2) -2*a(n-4)
k=3: [order 9] for n>11
k=4: [order 8] for n>10
k=5: [order 15] for n>20
k=6: [order 21] for n>27
k=7: [order 35] for n>43
Empirical for row n:
n=1: a(n) = 2*a(n-1)
n=2: a(n) = 3*a(n-1) +a(n-2) -6*a(n-3) -2*a(n-4) +4*a(n-5) for n>6
n=3: a(n) = 2*a(n-1) +a(n-3) -2*a(n-4) for n>8
n=4: [order 8] for n>11
n=5: [order 16] for n>21
n=6: [order 29] for n>35
n=7: [order 51] for n>62
