# Is this identity involving Stirling numbers of the first kind well-known?

I've been looking in vain (most books I came across give identities involving sums or recurrence relations, but do not give much attention to fixed values) for a reference to the following identity: $$S(n,n-3)={n \choose 2}{n \choose 4},$$ where $S(n,k)$ is the unsigned Stirling number of the first kind. Is this well-known, or too trivial to be mentioned anywhere?

It's not trivial, but the constant, 3, is just big enough not to be important enough to be even an exercise in a text. But it's perfect for OEIS as noted below. – Mitch Mar 2 '11 at 13:53
