Query: A short note on the noncoprime regular module problem   We consider a special configuration in which a finite group $A$ acts by
automorphisms on the finite group $G$, and the semidirect product $GA$ acts on
the vector space $V$ by linear transformations; and discuss the existence of
the regular $A$-module in $V_{_{A}}$.
