Let the vertex $\displaystyle A$ of a triangle $\displaystyle A B C$ be $\displaystyle (1,2)$, and the mid-point of the side $\displaystyle A B$ be $\displaystyle (5,-1)$. If the centroid of this triangle is $\displaystyle (3,4)$ and its circumcenter is $\displaystyle (\alpha, \beta)$, then $\displaystyle 21(\alpha+\beta)$ is equal to:
