R. H. Hardin, Table of n, a(n) for n = 1..238
FORMULA
Empirical for column k:
k=1: a(n) = a(n-1)
k=2: a(n) = 5*a(n-1) -4*a(n-2)
k=3: a(n) = 9*a(n-1) -4*a(n-2)
k=4: a(n) = 26*a(n-1) -97*a(n-2) +89*a(n-3) -18*a(n-4) +a(n-5)
k=5: [order 6] for n>8
k=6: [order 23] for n>24
k=7: [order 34] for n>37
Empirical for row n:
n=1: a(n) = a(n-1) +2*a(n-2)
n=2: a(n) = 4*a(n-1) +7*a(n-2) +a(n-3) -6*a(n-4) -5*a(n-5) for n>6
n=3: [order 21] for n>23
n=4: [order 93] for n>96
