A divisor of a number that is less than the number is called a "proper divisor".
For a given positive integer n, we are asked to evaluate the following summation:
This is equivalent to finding the product of the products of proper divisors of all integers from 2 to n.
For example for 
, we have:
, we have:

Really pretty simple, once you figure out which way to run the problem.
It's been two days, but my solution isn't showing up. It is size 37, but it is a real solution, no cheats apart from using an implicit ans to save four points, and an exploit of conversion from logical to numeric yielding 0 or 1. Any clues as to why it isn't showing up?
@GeeTwo I've had this happen once as well, a week or two ago. Some problem with the Cody servers, perhaps; I ended up resubmitting my solution, and the second one showed up.
