FORMULA
Empirical for column k:
k=1: a(n) = a(n-1) +a(n-2)
k=2: a(n) = a(n-1) +4*a(n-3) -2*a(n-4) for n>5
k=3: a(n) = a(n-1) +a(n-3) +2*a(n-4) for n>5
k=4: a(n) = a(n-1) +2*a(n-3) +a(n-4) +a(n-5) -2*a(n-7) for n>9
k=5: a(n) = a(n-1) +3*a(n-3) +a(n-4) +a(n-6) -2*a(n-7) -a(n-10) for n>14
k=6: [order 14] for n>19
k=7: [order 18] for n>24
