R. H. Hardin, Table of n, a(n) for n = 1..83
FORMULA
Empirical for column k:
k=1: a(n) = 2*a(n-1)
k=2: [order 14]
k=3: a(n) = 10*a(n-1) for n>5
k=4: [order 14] for n>16
k=5: [order 58]
Empirical for row n:
n=1: a(n) = 3*a(n-1) -3*a(n-2) +6*a(n-3) -6*a(n-5) +3*a(n-6) -3*a(n-7) +a(n-8)
n=2: [order 44]
n=3: [order 30]
