[seqfan] Re: Partitioning the sequence (?)

[zak seidov]

Joshua, 
this (with "s" at end!) is better 
but still is not what i need: 

<<DiscreteMath`Combinatorica`;Partitions[4]
{{4},{3,1},{2,2},{2,1,1},{1,1,1,1}}

while this is OK:
<< DiscreteMath`Combinatorica`; Permutations /@ Partitions[4]
{{{4}},{{3,1},{1,3}},{{2,2}},{{2,1,1},{1,2,1},{1,1,2}},{{1,1,1,1}}} 

- exactly what Franklin gave in his message below
(though in the reverse order).
thx, zak

That is we need some editing of 

%t A080577 <<DiscreteMath`Combinatorica`; Partition[6]

this way :

%t A080577 <<DiscreteMath`Combinatorica`; Permutations /@  Partitions[6] -
