Formula

a(1) = A088468(0); for n>1: a(n) = A088468(A003586(n)) and a(m) < A088468(m) for m < A003586(n).

Mathematica

f[0] = 1; f[n_] := f[n] = f[Floor[n/2]] + f[Floor[n/3]]; With[{max = 10^4}, f /@ Join[{0}, Sort@ Flatten@ Table[2^i*3^j, {i, 0, Log2[max]}, {j, 0, Log[3, max/2^i]}]]] (* Amiram Eldar, Jul 13 2023 *)
