Our purpose in this paper, is to show that several senders can jointly prepare a four-qubit |chi >-state to a remote receiver. By constructing some useful measurement bases, we first present two schemes to prepare an arbitrary |chi >-state with real coefficients or complex coefficients via the same quantum channel. Then, by using the permutation group the success probability is improved. Finally, the present schemes are generalized to multi-sender.
