Multipartitions of a multiset in Sage
Let L = [0,1,1,2,2,2,2,]. I want to generate all the multi-partitions of L in which each part can have repeated entries and the parts themselves can repeat in the partition.
For example, [[0],[1,2],[1,2],[2,2]] is one such partition of L.
Kindly help me with this. Thank you.
