R. H. Hardin, Table of n, a(n) for n = 1..178
FORMULA
Empirical for column k:
k=1: a(n) = 4*a(n-1) +2*a(n-2) -a(n-4)
k=2: a(n) = 10*a(n-1) +14*a(n-2) -6*a(n-3) -a(n-4)
k=3: [order 9] for n>10
k=4: [order 21]
k=5: [order 51] for n>54
Empirical for row n:
n=1: [linear recurrence of order 12] for n>13
n=2: [order 56] for n>58
