A free action of a group G on a row-ÿnite directed graph E induces an action \* on its Cuntz-Krieger C \* -algebra C \* (E), and a recent theorem of Kumjian and Pask says that the crossed product C \* (E) × \* G is stably isomorphic to the C \* -algebra C \* (E=G) of the quotient graph. We prove an
