  We analyze a region of fidelities for qubit which is obtained after an
application of a 1 -> N universal quantum cloner. We express the allowed region
for fidelities in terms of overlaps of pure states with irreps of S(n) (n =
N+1) showing that the pure states can be taken with real coefficients only.
Subsequently, the case n = 4, corresponding to a 1 -> 3 cloner is studied in
more detail as an illustrative example. To obtain the main result, we make a
convex hull of possible ranges of fidelities related to a given irrep. The
formalism allows to construct the state giving rise to a given N-tuple of
fidelities.
