n>1: a(n)=n iff n is even;
a(n)=A005836(n) iff n=6k3, k>0 (see A016945).
Comment from Jeremy Gardiner, Dec 28 2008: The following sequences all appear to have the same parity: A003071, A029886, A061297, A092524, A093431, A102393, A104258, A122248, A128975.

EXAMPLE

n=35=7*5='100011': 2^5 + 2^1 + 2^0 > a(35) = 5^5 + 5^1 + 5^0 =
3125+5+1 = 3131.
