R. H. Hardin, Table of n, a(n) for n = 1..199
FORMULA
Empirical for column k:
k=1: a(n) = a(n-1)
k=2: a(n) = 3*a(n-1) -2*a(n-2) +2*a(n-3) -2*a(n-4) -a(n-5)
k=3: [order 15]
k=4: [order 33]
k=5: [order 78]
Empirical for row n:
n=1: a(n) = a(n-1)
n=2: a(n) = 4*a(n-1) -3*a(n-2) +a(n-3) +6*a(n-4) -18*a(n-5)
n=3: [order 20]
n=4: [order 52]
