For a finite group $G$ denote by $N(G)$ the set of conjugacy class sizes of $G$. In 1980s J. G. Thompson posed the following conjecture: if $L$ is a finite nonabelian simple group, $G$ is a finite group with trivial center and $N(G)=N(L)$, then $L$ and $G$ are isomorphic. Here we prove Thompson's conjecture when $L$ is one of the groups $A_{10}$ and $L_4(4)$. This is the first time when Thompson's conjecture is checked for groups with connected prime graph.
Keywords: finite group, conjugacy class size, prime graph of a group.
