And since that simple case does not have a "closed expression", the more general certainly does not.
I mean by a product, so the expression represent a sum of all possible products of k distinct number between 1 and m. For instance k = 2 and m = 3 so can't we express it more simply without the sum ? Thanks for the helps.
