many-many maps

dunno the exact definition.

I will give an example i hope dat i din gave wrong one.

Suppose we have two sets

Set A has Sachin,Kohli,Sehwag

Set B has 50 s,100s,150s in ODIs

Now i can mapp Sachin to 50,100,150

And kohli to 100,50

And sehwag to 50,100,150

now we have many many mapping

dats we have more than one images for elements of set A,and preimages.
