## Abstract Let ${\cal G}$ be a fixed set of digraphs. Given a digraph __H__, a ${\cal G}$‐packing in __H__ is a collection ${\cal P}$ of vertex disjoint subgraphs of __H__, each isomorphic to a member of ${\cal G}$. A ${\cal G}$‐packing ${\cal P}$ is __maximum__ if the number of vertices belonging
