Distance-regular graphs with intersectuion arrays $\{42,30,12;1,6,28\}$ and $\{60,45,8;1,12,50\}$ do not exist

Koolen and Park obtained the list of intersection arrays for Shilla graphs with $b=3$. In particular distance-regular graph with intersectuion array $\{42,30,12;1,6,28\}$ is Shilla graphs with $b=3$. Gavrilyuk and Makhnev investigated properties of a graph with intersectuion array $\{60,45,8;1,12,50\}$. We proved that distance-regular graphs with intersectuion arrays $\{42, 30,12;1,6,28\}$ and $\{60,45,8;1,12,50\}$ do not exist.
