Let $W$ be the generalized Sato–Levine invariant, that is, the unique Vassiliev invariant of order 3 for two-component links that is equal to zero on double torus links of type $(1,k)$. It is proved that $$ W=\beta-\frac{k^3-k}6\,, $$ where $\beta$ is the invariant of order 3 proposed by Viro and Polyak in the form of representations of Gauss diagrams and $k$ is the linking number.
