# Number * SymmetricDivisorM0nbar -- multiply a symmetric divisor by a number

## Description

Let $Pic(\bar{M}_{0,n})_R^{S_n}$ denote the vector space of $S_n$-invariant divisors with coefficients in a ring $R$. Here, given an $S_n$ symmetric $R$-divisor $D$ on $\bar{M}_{0,n}$ and a number $c$, the function returns $cD$.
