Talk:Ordered partition of a set

From Wikipedia, the free encyclopedia

[edit] Name of the "opposite concept"?

Is there a name for partitions in which the order of the subsets does not matter, but the order of elements among each subset does? In other words: {1, 2} {3, 4} {5} and {3, 4} {1, 2} {5} would be equivalent, but would both differ from {1, 2} {4, 3} {5}. 164.15.127.77 (talk) 09:47, 29 April 2008 (UTC)
