| ### Keyword Abelian Groups ### Description In KASH3 we can work with abelian and symmetric groups. We can for example generate abelian groups and compute the direct sum. For elements of a symmetric group we can make use of cycles. ### Examples G := AbelianGroup([2,3,3]); H := AbelianGroup([5,3,3,7]); GH := DirectSum(H,G); FG1 := FreeAbelianGroup(3); FG2 := FreeAbelianGroup(5); G1G2:= DirectSum(FG1,FG2);
