  We propose a general formula for the perturbative large N superconformal
index of 5d quiver fixed point theories that have an AdS(6)xS(4)/Z(n)
supergravity dual. This index is obtained from the parent theory by projecting
to orbifold-invariant states and adding the twisted sector contributions. Our
result agrees with expectations from the dual supergravity description. We test
our formula against the direct computation of the index for Z(2) and Z(3) and
find complete agreement.
