GAMMA is an acronym for General Abstract Model for Multiset Manipulation. It is a programming paradigm relying solely on multiset transformation. [For more please consider DETAILS in the comment.]

How to use:
These four small programs can be used:
- prime(N): prime numbers
Returns all prime numbers Pi up to N by prime_M(Pi).
- fact(N): factorial
Returns the factorial N! by fact_M(N!).
- sp(L1,L2): partition into sets
Partitions the elements of L1 and L2 into sets S and T (with size(S)=size(L1)) so that all elements from S are smaller than those from T. E belongs to S is represented: sp_M((E,inS)). E belongs to T is represented: sp_M((E,inT)).
- so(L): sort
List L (n elements) is sorted to [S1,S2,..Sn]: so_M((i-1,Si)).
