$m$-submultisets and $m$-permutations of multisets elements
The article is devoted to two classical combinatorial problems on multisets, which in the existing literature are given unjustifiably little space. Namely, the calculation of the number of all submultisets of power $m$ for an arbitrary multiset and the number of $m$-permutations of such multisets. T...
