R. H. Hardin, Table of n, a(n) for n = 1..95
FORMULA
Empirical for column k:
k=4: a(n) = 18*a(n-1) -91*a(n-2) +469*a(n-3) -919*a(n-4) +2152*a(n-5) -93*a(n-6) +a(n-7)
k=5: [order 9] for n>10
Empirical for row n:
n=2: a(n) = 5*a(n-1) -4*a(n-2) -5*a(n-3) +9*a(n-4) +12*a(n-5) for n>6
n=3: [order 49] for n>52
