#F LoadDifferenceSets( <v>, <n> )

## <#GAPDoc Label="LoadDifferenceSets">
## <ManSection>
## <Func Name="LoadDifferenceSets" Arg="v, n"/>
##
## <Description>
## Returns the precomputed list of all difference sets up to equivalence
## for the group <C>SmallGroup(<A>v</A>, <A>n</A>)</C> stored in the
## package library. An error is thrown if no precomputed list is available.
## Note that the listed difference sets are specific to
## <C>SmallGroup(<A>v</A>, <A>n</A>)</C>, as &GAP; may label entries of
## other isomorphic versions of the same group differently.
##
## <Example><![CDATA[
## gap> LoadDifferenceSets(15, 1);
## [ [ 1, 2, 3, 4, 8, 11, 12 ] ]
## gap> G := SmallGroup(15, 1);; H := AbelianGroup([15]);;
## gap> IdGroup(G) = IdGroup(H);
## true
## gap> IsDifferenceSet(G, [1, 2, 3, 4, 8, 11, 12]);
## true
## gap> IsDifferenceSet(H, [1, 2, 3, 4, 8, 11, 12]);
## false
## ]]></Example>
