Query: Testing isomorphism of circulant objects in polynomial time   Let ${\frak K}$ be a class of combinatorial objects invariant with respect to
a given regular cyclic group. It is proved that the isomorphism of any two
objects $X,Y\in{\frak K}$ can be tested in polynomial time in sizes of $X$ and
$Y$.
