Query: The Cayley isomorphism property for the group $C_4\times C_p^2$   A finite group $G$ is called a DCI-group if two Cayley digraphs over $G$ are
isomorphic if and only if their connection sets are conjugate by a group
automorphism. We prove that the group $C_4\times C_p^2$, where $p$ is a prime,
is a DCI-group if and only if $p\neq 2$.
