COMMENTS
Let m = Product p_j ^ a_j be the standard prime factorization of m. The additive excess of m is defined to be Sum||p_j ^ a_j|| - ||m|| where ||m||=A005245(n) is the complexity of n.
The n-th term of this sequence is the least number m with additive excess n.

EXAMPLE
||253||=17, ||11||=8, ||23||=11. 11 + 8 - 17 = 2. The second term is 253.
