A group of four processes P0-P3 sends out multicasts in a run as shown below. The group is using FIFO ordering for multicasts. All four processes start with vectors containing all zeros, i.e., each process starts at 0, 0, 0, 0. An arrow shoes a message, and each darkened circle shows a process instruction. Answer the following question. The sequence vector associated with the send event of the only multicast that P3 sends out, as a comma-separated list (without the brackets), is
