R. H. Hardin, Table of n, a(n) for n = 1..288
FORMULA
Empirical for column k:
k=1: a(n) = 8*a(n-1) -7*a(n-2) -56*a(n-3) +120*a(n-4) -64*a(n-5)
k=2: [order 17]
k=3: [order 17] for n>18
k=4: [order 80] for n>85
Empirical for row n:
n=1: a(n) = 8*a(n-1) -7*a(n-2) -56*a(n-3) +120*a(n-4) -64*a(n-5)
n=2: [order 19]
n=3: [order 21]
n=4: [order 86] for n>93
