FORMULA
Empirical for column k:
k=1: a(n) = a(n-1).
k=2: a(n) = a(n-1) +a(n-2) for n>3.
k=3: a(n) = a(n-1) +a(n-2) for n>3.
k=4: a(n) = 2*a(n-1) -a(n-3).
k=5: a(n) = a(n-1) +a(n-2) +a(n-3) +a(n-5) -a(n-6) -a(n-7) -a(n-8) for n>9.
k=6: a(n) = 3*a(n-1) -2*a(n-2) +a(n-3) -2*a(n-4) -a(n-7) +2*a(n-8) for n>9.
k=7: [order 14] for n>15.
