Details:
A multiset of k elements out of n is a sorted list of k elements of [1,...,n], with repetitions allowed.
This is a fast low-level combinatorial class, with a simplistic interface by design.
count – number of multisets
combinat::multisetsNK::count(nonnegative integer , nonnegative integer )
Returns the number of multisets of k elements out of n.
generator – generator for the multisets
combinat::multisetsNK::generator(nonnegative integer 
, nonnegative integer 
)
Returns a generator for the multisets of k elements out of n, in lexicographic order.
list – list of the multisets
combinat::multisetsNK::list(nonnegative integer 
, nonnegative integer 
)
Returns the list of all the multisets of k elements out of n, in lexicographic order.
random – random multiset
combinat::multisetsNK::random(nonnegative integer 
, nonnegative integer 
)
Returns a random multiset of k elements out of n.
Here is the list of all the multisets of 2 elements out of 5:
