Subsets
Subsets[list]
gives a list of all possible subsets of list.
Subsets[list, n]
gives all subsets containing at most n elements.
Subsets[list, {n}]
gives all subsets containing exactly n elements.
Subsets[list, {nmin, nmax}]
gives all subsets containing between 
and 
elements.
Subsets[list, nspec, s]
limits the result to the first s subsets.
Subsets[list, nspec, {s}]
gives if possible the 
subset.
Details
- Subsets[list] gives the power set of list.
- Subsets[list] orders subsets with shortest first, and later elements in list omitted first.
- If the elements of list are in the order returned by Sort, then the complete result from Subsets[list] will also be in this order.
- Subsets[list, All] is equivalent to Subsets[list].
- Subsets[list, {nmin, nmax, dn}] gives subsets containing
, 
, ... elements. - Subsets[list, nspec, spec] gives the same result as Take[Subsets[list, nspec], spec], provided that the elements specified by spec are present.
