Unique representation of 5-number sets with values 1-13

Question

From a simulation I get 5 numbers 1-13. The nature of the simulation is that I do not get the numbers ordered. The value/rank of the the tuple is not order dependent 5 5 5 2 2 = 2 5 2 5 5. Values can repeat but they can repeat at most 4 times (it is a deck of cards). As it turn out there are 6175 combinations. Calculate the value of the tuple is expensive but it is pretty cheap to just generate the tuples in value order - save that and do a dictionary lookup. Without sorting the numbers what is the smallest number to uniquely represent the 5 number combination and how to generate that number?

Right now I just raise 5 to the 0-12 power and add the 5 as a proof of concept and it works. But that is fairly expensive and uses 32 bits. I want to get the bits and compute down. How might I do that?

Yes I have had few questions on this subject but I promise to make this my last.

In a related question got an answer for 5 numbers 1-52 in 27 bits using some magic numbers and XOR. I cannot figure out how to create those magic numbers for 1-13.
