R. H. Hardin, Table of n, a(n) for n = 1..125
FORMULA
Empirical for column k:
k=4: a(n) = 16*a(n-1) -12*a(n-2) +87*a(n-3) -918*a(n-4) +61*a(n-5) -a(n-6)
k=5: [order 7] for n>8
k=6: [order 50] for n>51
Empirical for row n:
n=2: a(n) = 5*a(n-1) -5*a(n-2) +5*a(n-3) +8*a(n-4) for n>5
n=3: [order 31] for n>34
