Query: Identifying codes of Cartesian product of two cliques   An identifying code in a graph $G$ is a dominating set $C$ such that the
closed neighborhood of each vertex in $G$ has a distinct intersection with $C$.
In 2008, Gravier et al. determined the minimum cardinality of an identifying
code of the Cartesian product of two cliques with the same size. In this note,
we generalize this result to the Cartesian product of any two nontrivial
cliques.
