FORMULA
Empirical for column k:
k=1: a(n) = a(n-1)
k=2: a(n) = 6*a(n-1) -7*a(n-2) -6*a(n-3) -5*a(n-4) +12*a(n-5) +4*a(n-6) -4*a(n-8)
k=3: [order 14] for n>19
k=4: [order 15] for n>21
k=5: [order 19] for n>30
k=6: [order 21] for n>34
k=7: [order 23] for n>38
Empirical for row n:
n=1: a(n) = a(n-1)
n=2: [order 9] for n>10
n=3: [order 8] for n>13
n=4: [order 10] for n>16
n=5: [order 12] for n>19
n=6: [order 14] for n>25
