R. H. Hardin, Table of n, a(n) for n = 1..364
FORMULA
Empirical for column k:
k=1: a(n) = a(n-1)
k=2: a(n) = 3*a(n-1) -a(n-2)
k=3: a(n) = 4*a(n-1) +a(n-2) -2*a(n-3)
k=4: a(n) = 9*a(n-1) -8*a(n-2) -14*a(n-3) +4*a(n-4) +4*a(n-5) -a(n-6)
k=5: [order 13] for n>15
k=6: [order 26] for n>28
k=7: [order 43] for n>47
Empirical for row n:
n=1: a(n) = a(n-1) +a(n-2)
n=2: a(n) = 3*a(n-1) +a(n-2) -2*a(n-4) for n>6
n=3: [order 10] for n>12
n=4: [order 36] for n>40
