hi there,

is there any way to get mathematica to return the actual partitions of
an integer? the only functions related to this, (e.g.
http://mathworld.wolfram.com/PartitionFunctionP.html) only return the
*number* of partitions, not the actual partititons (including
permutations) themselves.

e.g. for 4, i'd like a function to return
 {{1,1,1,1}, {2,1,1}, {1,2,1}, {1,1,2}, {3,1}, {2,2}, {1,3}, {4}}

with the ordering of the partitions not being important

cheers,
Shug
