R. H. Hardin, Table of n, a(n) for n = 1..98
FORMULA
Empirical for row n:
n=2: a(n) = 2*a(n-1) -2*a(n-3) +a(n-4)
n=3: [order 10]
n=4: [order 18]
Empirical quasipolynomials for row n:
n=2: polynomial of degree 2 plus a quasipolynomial of degree 0 with period 2
n=3: polynomial of degree 5 plus a quasipolynomial of degree 3 with period 2
n=4: polynomial of degree 9 plus a quasipolynomial of degree 7 with period 2
