Can the states of the W-class be suitable for teleportation?

Entangled states of the W-class are considered as a quantum channel for teleportation of an entangled state and as well the state to be teleported via a multiparticle quantum channel. Using an introduced unitary transformation in the teleportation schemes based on the multiparticle Greenberger-Horne-Zeilinger channel it is found a set of protocols main feature of which is a collection of non-local recovering operators.
