Dear S'ers:

Can anybody help me in solving the following problem:
I have a series of complex numbers z[i], i=1,....,N
There are numerous repetitions in these numbers. For example, N is of order
1,000,000. However, only ~20,000 of z[i] are different. I need to assign a
unique name or number to each of z[i] in such a way that equal z have the same
For example, I have


I need to name them as follows

In order to get the result until the end of this century, I want to avoid
looping, and especially double looping.

Thank you
