Can there be a closed form representation for the expression

$$ 1+ \sum_{m=1}^{2(n-1)} \prod_{k=1}^{m} \dfrac{2(n-1)-(k-1)}{( ^nC_2 -k)} $$

It would simplify working with some equations I have. The current form in its full expansion is way too cumbersome.

    Please don't have titles that consist of nothing but Markup/$\LaTeX$. Also, a big expression is not a very informative title.2012-02-24
