Description
The value of the elementary symmetric function evaluated at 1. The statistic is $e_\lambda(x_1,\dotsc,x_k)$ evaluated at $x_1=x_2=\dotsb=x_k=1$, where $\lambda$ has $k$ parts. Thus, the statistic is equal to $\prod_{j=1}^k \frac{(k)_{\lambda_j}}{\lambda_j!}$ where $\lambda$ has $k$ parts.
