How do I show in sage that

 (1234)=(12)(13)(14)

I tried:

 PermutationGroup([[(1,2)]]) * PermutationGroup([[(1,3)]]) * PermutationGroup([[(1,4)]])

but sage says:

 For implementing multiplication, provide the method '_mul_' for Permutation Group with generators [(1,2)] resp. Permutation Group with generators [(1,3)]

 Permutation([[(1,2)]]) * Permutation([[(1,3)]]) * Permutation([[(1,4)]])

How do I show in sage that

 (1234)=(12)(13)(14)

I tried:tried make use of:

 PermutationGroup([[(1,2)]]) PermutationGroup([1,2]) * PermutationGroup([[(1,3)]]) * PermutationGroup([[(1,4)]])

but sage says:

 For implementing multiplication, provide the method '_mul_' for Permutation Group with generators [(1,2)] resp. Permutation Group with generators [(1,3)]

But (12) is not a group actually - but permuation. So I tried:

 Permutation([[(1,2)]]) * Permutation([[(1,3)]]) * Permutation([[(1,4)]])
PermutationGroup([1,3])

but it gives:doesn't do what is needed.
