What are the possible orders of message delivery to each process if the messages are causally related as m11 -> m21 -> m12 -> m22 and the multicast is (i) FIFO, (ii) causal, and (iii) atomic?

Suppose a multicast group currently is participated by two processes: P1 and P2. Suppose P1 multicasts m11 then m12, P2 multicasts m21 then m22.

Now we are reduced to 1 order: m11, m21, m12, m22
